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!
