Use this activity to help your students practice adding and subtracting integers!
Devin and Jamie were doing their math homework together. They worked the problems out on their own and then compared answers. There were several problems that they disagreed on. It is up to your students to determine who is correct and why!
Students not only have to solve each word problem to determine who is correct, but must also explain how they know.
CCSS.Math.Content.7.NS.A.1 Apply and extend previous understandings of addition and subtraction to add and subtract rational numbers
