This is a VERY thorough packet! In its 8 pages, it includes notes and examples, practice using number lines and two-color counters, and application word problems. There is plenty of room for students to show their work. Using models to add and subtract integers is a 7th grade objective in Texas, and this lesson complements a popular curriculum program in the state. I also have a packet for multiplying and dividing using models. For a little more money, you can buy the Word version of this packet. You can make changes as you see fit. I only ask that you not resell it as your own.
