Bringing Integers to Life!

When I was in my first year of teaching, I had stumped upon this activity somewhere.  I wish I tracked everything during that time but lets be serious, I was barely keeping my head above water.

The concept behind this integer activity is to get kids out of their seat moving while seeing if they make any connections from adding integers to subtracting integers.  



Directions: 
1. Start on the first number in the problem
2. Face the negative numbers for subtraction and the positive numbers for addition. 
3. Walk forwards for positive number and backwards for negative numbers. 

Check out this short clip.   Kids love this activity!  It isn't perfect so I haven't posted it on TPT yet.  If you would like it, leave a comment and I will send it to you!

This year kids cheered when I rolled out the GIANT number lines.  It really has nothing to do with anything but it sure felt good that they were excited!

We've hit Integer Season!

An important topic in 7th grade is integer operations.  This is the first time that adding, subtracting, multiplying and dividing integers are formally introduced.  I went about it differently this year than 2 years ago.  CMP3 suggested using chips to introduce addition, so that's what I tried!

I really liked it.  I felt that students really grasped the idea of adding integers.  They could see when adding a positive and negative number which had more and that determined the sign of the sum.

I also found that this concept really helped those struggling students.  This is a picture I snapped while helping a student one on one build her confidence in solving. 

After the introduction, I set students on a journey with a partner to answer questions from our online book.  This is where I saw students helping students the most.  They were explaining it in terms that made sense to them.  




The journey through integers is not always easy but I highly suggest using chips.  After using chips, I also taught students how to use the number line to add integers.  I left it up to the students which way of reasoning worked for them and never actually taught a formal way to add integers.  I would say 93% of students are confident in their integer abilities.  The other 7% I am working with daily.  

What are some methods of teaching integers you have tried?  Even if they didn't work, we can always learn from mistakes!
