Adding integers with the same sign means both numbers have either a positive or negative sign. When adding two integers with the same sign, add the two numbers together and keep the sign. For example, 5 + 4 = 9 and -7 + -5 = -12

Adding two positive integers together is just the same as counting up from the first integer to the second integer. When adding two integers with the same sign, the result will always have the same sign as the two integers being added. Adding two negative integers together can be thought of as taking the difference between the two integers.

Question: You are two friends who are helping each other understand how to add integers with the same sign. What strategy do you use to solve the problem? Clues: • Integers with the same sign can be added by combining the two numbers. • The sign of the answer will be the same as the integers you are adding. • Remember that integers with different signs have to be subtracted. In pairs: Select and solve one of the tasks: A. Work together to solve an example problem of adding two integers with the same sign. B. Create a drawing to visually explain your strategy for adding integers with the same sign.
