Fractions, Decimals and Percents, oh my!

I know, I know - it's been forever! I have been so busy with work that most days when I got home I didn't even want to think about writing about it - and then, on those days where I was feeling it, I either had blogger's block or forgot to take pictures of the cool things we were working on in class!

This has been a busy few months for me, but I'm very proud of how our math notebooks are coming along.  My only problem is that I'm running out of space!  A lot of my students only have a few pages left in the first section of their notebooks, and we are already using the 2nd and 3rd sections for other things.  My plan was to use the first section for notes and foldable, the second section for vocabulary, and the third section for warm ups.  I have not been using the vocabulary section like I wanted to, so I think I am just going to have students move to that section when they run out of room in the first section.  Next year I think I will either request a five subject notebook, or find a different way to work the vocab section (maybe a running definition sheet instead of Frayer's model?)

We have covered quite a few topics since my last post - integer operations, writing algebraic equations and expressions, solving algebraic equations (one and two step), and graphing functions.  My plan is to go back over winter break and cover each of those in a separate post. 

Right now, we are working on converting between fractions, decimals and percents.  We made a booklet showing how to convert between each that students could reference later.  I also gave students some benchmark fractions that I expect them to know (1/2, 1/3, 1/4, 1/5, 1/8, and 1/10).  These are some very standard fractions that make student's lives so much easier if they just know them, so I give them to students and we practice them.


Front of the booklet with notes on the side


Inside of booklet - we wrote how to inside the front flap, and examples on the other side.


Then, because I LOVED how simple this was, we used this idea from Math = Love. (I could not for the life of me find the exact post - I originally saw this on pintrest, but it didn't link to the original post.) Anyways, I added the conversion back to decimals because I feel students need to know it, but didn't add the other two because I thought it would mess up the simplicity of it. 


Conversion Triangle

Finally, we played a game I made up called 'Bazinga!'  I loosely based it off of the game, 'Kaboom!' created by Carol S. that I purchased last year from Teachers Pay Teachers and used for another topic. There were quite a few things I changed about the game to better fit my style of teaching, so I decided I needed to change the name.

In Bazinga, there are three types of cards - Bazinga! cards, Double Points cards, and the question cards.  If students pull a Bazinga card they lose all of their points. If they pull a double points card they get to take it back to their seat and use it whenever they want to double the points they earn that round (not all of their points).  Finally, the question cards can be on whatever topic you want - this time I wrote either a decimal, a percent or a fraction on the cards.  Students had to come up with the other two forms of the number. (So if a decimal was on the card, they had to write an equivalent fraction and percent.)  The first team to hold up their whiteboard with the correct answer earns 20 points, the second team earns 10 points, and the third team earns 5 points (they keep track of their own score).  The first team also selects the next card from the deck.  Students love it (especially when the winning team pulls a Bazinga! card and loses all of their points), it provides great practice, and immediately allows me to see who is/is not getting it.  I can also immediately correct any misunderstandings and confusions that come up.  I am selling this game in my Teachers Pay Teachers store - just click the picture below.



For homework I had students fill in a chart that had three columns (fraction, decimal or percent).  I gave one form of the number, and had the students give the missing two. If you would like a copy of this, just click on the picture below! 


Homework Assignment

We are continuing to work on this, but I found that the game helped most students grasp the concept. It was amazing the amount of growth I saw from the beginning of the game to the end of the game.  What are some ways you teach changing from decimals to percents to fractions?

Math Games with a Deck of Cards

Sorry it's been so long - I'm just ridiculously busy at school with department chair, our incoming one-to-one laptop program (which I'm now on the teacher committee for), and life in general.  Right now I am taking a quick break from cleaning out our fridge - which busted this weekend while I was out of town and resulted in over $300 worth of food being ruined.  (I am about in tears throwing out everything from our freezer - with the hubby out of town I literally had enough food to last me through Thanksgiving.) 

Anyways, I have been promising a post on all the math games that I teach students that can be played with a deck of cards.  Basically they are all just variations of the same game - war - just with slight modifications. You can play this game to practice multiplication facts, addition facts, integer addition rules or multiplication integer rules. 

To play, students divide a deck of cards in half and flip over the top card from their pile (just like the traditional game of war).  The winner of the two cards is the first person who calls out the product  of the two cards.  For example, if I flipped a 6 and Joe flipped a 5, the first person who called out 30 would win both cards.  I have my students play with face cards - Kings are 0, Aces are 1, Jacks are 11, and Queens are 12.  I know it's a bit non-traditional to have Kings be 0, but I am not really worried about students knowing their 13 facts, so I make it 0.  Sometimes, when I am working with lower grades or lower level students I have them take out all of the face cards.

A modification to this game if you don't want to focus on speed, is to have each student flip two cards, and then whoever has the greater product wins all four cards.  For example, if I flipped a 6 and a 3, and Joe flipped a 4 and a 5, Joe would win all four cards since 4 times 5 (20) is greater than 6 times 3 (18).   Of course, in either version of the game, if you have a tie you play war - three cards face down and then flip the next card (or two cards) and whoever wins that match up wins all of the cards. 

To play so you are practicing addition facts, simply have students find the sum instead of the product.  If you want students to play using integer rules, have them play the same way, but this time red cards are negative and black cards are positive.  When I first introduce this game with integers I usually have students take out the face cards - they are so focused on keeping the colors straight that I don't want to confuse them with the face cards too. 

These are such easy, simple games to practice very essential skills and the kids love them.  Sometimes I have them as a station activity, or if I finish a lesson early I know I have them as a back up to fall back on.

Do you have games in your classroom that are old faithfuls?

Lovin' My Stations!

I mentioned in an earlier post about how I love stations, and I am trying to use them more in my class this year instead of avoiding them like the plague last year.  You know why I love stations so much?  Because after the first time we used them this year (see my post on that here), my students have been asking when we are going to use them again - and today, when they walked in and saw that we were doing stations for the 2nd time this week, they actually said (out-loud), "Stations! Yes!"  Now, I don't know about most of you but when I get my students to exclaim in excitement about something they get to do with math - well... it's fabulous!

I am going to tell you about the first set of stations we did this week, and leave the second set until later.  We are working on integers right now, and I really wanted them to have some more practice with adding and subtraction before we moved on to multiplying and dividing.  I did not want to just use worksheets because they're so boring.  An entire class period of worksheets sounded miserable, and I'm the teacher!  Anyways, I planned out four stations for the students to cycle through.  I love that even though the last time we did stations was a month ago, my students still knew how the system worked.


This is how I organize my station rotations.  Cute? No. Simple and effective? Yes.
(Just ignore the poll in the top corner - that was for something else I was keeping track of)
These are not the stations I used for this post, but you can see how I organize them in this picture.

My first station was an adding and subtracting integers memory game.  I laid all the cards out on the table face down and ready to go for the first group.  Every group after that was responsible for putting the cards back in the same way they found them so the next group was ready to play the minute they started the station.  Students took turns flipping over two cards - they had to say what the answer was to every expression they flipped over.  If they found a match they kept the cards and went again.  If they didn't find a match, it was the next player's turn.  This game always starts a little slow, but once they can start remembering where the cards are it gets really fun as they can't find the match but the next person can.  I am selling this game on my TeachersPayTeachers store.

Memory Game all laid out and ready to play!

The second station was very similar to a station I did last time (algebraic expression posters) - but this time they were only practicing the order of operations.  This is something that we already covered, and students had a test on but it is so important that I like reviewing constantly throughout the year.  Students solved each of the expressions on the poster and moved post-it notes labeled 1-9 around to show the answer.  Each post-it note gets used exactly one time.  If they find they need the same number or that they haven't used a number then they know they've made a mistake.  After they are done, I quickly check them and have them get a new poster to complete.  I have them work on these in pairs, and I love hearing their conversations as they discuss the correct order to solve the problems.

One of the posters that they worked on!


The third station was also very similar to a station I did last time (self-correcting excel spreadsheet).  This time they were practicing adding and subtracting integers.  If you want a copy of this, just click on the image below.  It looks really funny on google drive, but downloads correctly.  Students solve each of the problems, and type the answer in the second column.  They then check the third column to see if they are right or not.  I was planning on having them go to www.multiplication.com (LOVE this site, especially since I still have students who don't know their facts!), but our Internet was down.  (Don't you hate when that happens?!?)  Instead I had them work on their homework - an adding and subtracting integer worksheet. It wasn't nearly as entertaining, but the kiddos all seemed to appreciate having time to do their homework in class. 


This is the Adding and Subtracting Integers spreadsheet they did - see how in the third column it tells them whether they are right or wrong?


The fourth station was my favorite.  My students have done some graphing before, but never with all four quadrants of the coordinate plane.  We did a coordinate graphing picture earlier in the unit to practice, but I wanted to do a little more with it so I created this game.  It's battleship with the coordinate plane!  And, I made it with a Pirates of the Caribbean theme!  All of the ships are named after ships from the movie series, and my students LOVED it!  They were either the pirates or the royal navy, and hid their respective ships on their coordinate plane.  Then they took turns trying to find their opponent's ships by calling out coordinate pairs and marking them on their board.  I originally made a version that can be printed out on paper where you would break everyone into pairs, and pass out a pirates sheet to one player and a royal navy sheet to the other player.  Then, realizing that this would be a lot more fun with dry erase markers, I made a more permanent version using manila folders and laminating them.  Then, because I was so excited about it, I decided to sell it in my TeachersPayTeachers store.


The front of the folders - are you going to be the Pirates, or the Royal Navy?


My brilliant students actually figured out that if you use a binder clip the board would stand up on its own.  They're geniuses. 

Playing the game!

My second time with stations went really well - I just need to remember to set the timer at the beginning of each station!  Also, this was a good reminder that I always need a back up in case the Internet is down and I've planned an activity using it - this is when having good 'go-to' games are awesome (which I will talk about in a later post, I swear)!


What are some activities you use to practice integers? Do you have any 'go-to' back up activities for when technology decides not to cooperate?

Starting Integers

When I had my students write their goals at the beginning of the year, I had quite a few of them that said they wanted to learn how to add negative numbers (or something else to do with integers).  After reading those, I was really excited to start our unit on integers.



Our Foldable - Click Here for a Copy

 
In our standards, 7th grade is where students are introduced to integers for the first time, so I wanted to make sure we started with activities that would give students an understanding of integers.  I had the students make this foldable for their notebook where we looked at opposite versus absolute value.  Students are constantly mixing the two up, and always giving an opposite when they are look for absolute value.  We discussed that absolute value was the distance for zero, and as usually a lot of the students claim that absolute value just turns the number positive, so we had a really good discussion on why it became positive.  My students all know about Ferris Bueller's Day Off now - I really wanted to show them the clip of trying to turn the odometer backwards, but I'm not sure the language would be appropriate so we just talked about it.

 
I messed up the positive one, but didn't want to waste more masking tape
 
In addition to the foldable, I made a number line out of a piece of masking tape in the hallway and had students walk out the absolute value.  A classmate would give them an integer between -15 and 15, and they would walk the distance to zero on the number line.  I think they thought it was a little ridiculous, especially those that 'got it' but I had very few students who messed up absolute value on the practice sheet they did for homework, so I'm calling it a success.

I also made a set of index cards with random numbers from -50 to 50 on them.  I first had students find their opposite in the classroom (which I think I'm going to use as a way to make random groups from now on) and then I had the students line up in order from least to greatest without talking.  This was really good practice for them to move around and practice ordering integers. 
 
We've continued to practice integer number sense in their warm ups and as we are discussing integer operations, but they seem to have a good grasp on the concept, which makes me really happy. 

We've moved on to integer operations, and I am thrilled with how those lessons are going, but I'll talk about that in another blog post!

Professional Development Day

We had our first professional development day this year, and I have to say I am very excited about how it went.  This year our school is piloting a one-to-one laptop initiative, and while I am super excited about getting those laptops into our student's hands, not everyone is.  We have a few teachers who are pretty anxious about the whole thing, but our ET (technology teacher) is AH-mazing, and got the ball rolling early.  The computers won't get here until January, so we have some time to get some PD in before the day arrives.

We spent the morning discussing in teams and departments logistical issues and curriculum issues.  There are a lot of schools that have implemented one-to-one laptop programs, but there is surprisingly little information on the how-to involved.  We often feel like we are making this up as we go.  There were a lot of good discussions in our teams and departments, which then translated into a good discussion as a faculty.  Almost all of the concerns we had were answered, and the few that weren't are going to be looked into. 

In the afternoon we had a variety of different sessions we could choose between, and they were awesome!  I think everyone I talked to learned something new and cool - and almost everything was presented by someone who teaches at our school!  I learned about a new software program called Netsupport where you can control all of your student's computers from your computer, or just monitor their work or basically whatever you want to do.  Can you imagine how awesome that is going to be when every student in your class is going to have their own laptop?  Now, I can look at everyone's screen at once and send messages to students who are off task or who need help.  I think that alone alleviated a LOT of concerns about classroom management. You can also turn off all the student's monitors just by clicking a button so they can't continue to work when you need to give directions, and about a hundred other awesome things.

Another session I went to was with the SmartBoard.  I used a SmartBoard in Virginia almost daily, but wasn't able to use mine here until this year.  I had seriously forgotten a LOT!  Another math teacher in our school was presenting on it, and she seriously knows her stuff!  It was awesome!  I relearned a few tricks, and learned some new ones that I'm excited to try out.  In fact, after this session I immediately went back to my room and reworked my lesson for tomorrow so that I'm using the SmartBoard to introduce adding integers.  It was also very entertaining listening to some of the teachers who had never used a SmartBoard get super excited about all of the cool things she was teaching us how to do.

I feel like too often professional development is a waste of time where we aren't learning anything that we can take back to our classrooms and implement.  A lot of times PD become discussions on theory and best practices - but without any ideas on how to implement those best practices.  I loved that today  I learned something that I can use tomorrow - this is how PD should be.

Changing Routines

I started a new system this year for students who were absent to get their missing work.  My plan was to have a expandable file folder with a section labeled for each class in my student office area.  I was going to write the name of each absent student on the paper, and then file it in the correct section so students would know to look there for the papers they missed.  It sounds like an excellent plan, and if used properly, probably works like a dream.  If you use it properly.  Which I don't.  The first month of school is over, and after about the first week I could not for the life of me remember to put the names on the papers, let alone file them.  And on top of that, my students who were present would go in there and take another copy because they lost original.  So, needless to say, the plan wasn't working - so, I changed it.

In my opinion, one of the biggest mistakes you can make is to keep trying to use something that just doesn't work for you simply because you're worried about the students having to learn a new routine or procedure.  I would say that trying to change something you've been doing all year in the last month might be a little nutty, but if you realize your system isn't working then don't keep using a broken system!  Fix it! Improve it, rearrange it, reorganize it, get rid of it completely - whatever you need to do to make your life easier in the long run.  Working with a broken system is only going to cause you headaches and frustration - and we get enough of both of those things as it is.  It sounds really simple, and a lot of people are probably thinking, "well, no duh" but I have meet so many people who just keep doing something the same way because they don't want to make the effort to change it.

My new system is still using the very pretty expandable file folder I bought (didn't want to waste it), but now I have the sections labeled for the type of activity/assignment it is.  I have a section for extra homework assignments, extra class work assignments, extra notebook activities, for new students, and for notebook setup. There is a lot of student turnover in DoD schools, so I will definitely end up with more than a few new students as the year goes on.  Now, instead of having to write names on papers and sort them into the correct section, I can just place the extras I have after the lesson into the appropriate slot.  This has already helped me stay organized (now I know where all my extras are), and has helped the students find exactly what they are looking for.  I still have to help students find their missing work sometimes, but this way is a LOT easier for me - and that means less headaches.

Order of Operations Foldable

My students have been working with order of operations since they were in fifth grade, and it amazes me every year how they can recite the order of operations back to me, but when it comes to applying it - 'poof!' - it's like they've never heard of it before!  I've also found that often students recite the order as parenthesis, exponents, multiplication, division, addition, subtraction without any reference to the fact that multiplication and division/addition and subtraction are completed from left to right and that they aren't two different steps.  They also don't know what to do with roots when they encounter them, and problems where a sum is being divided by another sum. 

I still needed to review the order of operations with the students, but I wanted to make sure I would give them a resource they could refer back to throughout the year and into high level maths if necessary.  I'm a firm believer that just because I'm not teaching something this year doesn't mean I should avoid it if it will cause confusion later.  For example, when I taught fifth grade I didn't tell students you can't subtract five from three (3 - 5) because you can - I just told them that it would be a negative answer and they would learn about that in middle school.

PEMDAS Flipbook
I went a searching online and found this great idea for a foldable from the blog Math = Love.  I made my own version mainly because I wanted the words to be preprinted.  We cut them out and glued them into our math notebooks, and then took the notes about each step on the inside, behind the preprinted words.  On the side that was pasted down we completed a practice problem showing the order of operations. 

We wrote notes for each step on the inside
We solved a practice problem on the other side

The students then completed a practice sheet using the order of operations. My students did fairly well with it - a couple of missteps but nothing too bad.  However, the next day in our stations as we were working on our algebraic expressions posters (I talked about them here) some kept forgetting to use the order of operations.  I would ask them what does the order of operations say to do, and I had more than one student who looked at me with eyes opened wide and asked, 'this is order of operations?!?'  We definitely need to keep working on it.  :)  If you want a copy of this flipbook, click here.

 In other news, I took the plunge and opened a teachers pay teachers store, which you realize if you tried to download this flipbook..  I only have three products on there so far (two of which are free), but it was really awesome to wake up this morning and see that someone had given one my freebies 4 out of 4 stars!  Someone likes something I made!  I know, I'm a bit of a dork, but I am very excited about this new endeavour.  I don't expect to ever be making thousands of dollars like some of those AMAZING teachers, but I think I am going to enjoy getting the feedback from other teachers on things I've made - and since I'm a bit of a perfectionist it will encourage me to really think out a lot of the details of things I'm making so I can sell them on there later!  You can visit my teachers pay teachers store here.  (Even if you don't want to buy anything, you can go see what I'm talking about.)  The site overall is a wealth of fantastic resources, and if you aren't using it yet (and you're a teacher), I would encourage you to take a look.  A lot of the stuff on there is free too!

How do you get your students to remember to use the order of operations with everything?  What do you think about my teacher store?
