Original Promptcreate new station activity for Subtracting Integers as Adding the Opposite with an exi ticket
This learning resource focuses on the concept of subtraction as the addition of the opposite integer. Students are introduced to a systematic approach for converting subtraction problems into addition problems to simplify the process of finding sums. The key strategy involves three steps: (1) keeping the first number, (2) changing the subtraction sign to addition, and (3) changing the sign of the second number to its opposite. The document includes a worked example for clarity, followed by independent practice problems to reinforce understanding. Students rewrite various subtraction expressions as addition expressions before calculating the sums. An exit ticket prompts students to apply their learning by solving a final problem while reflecting on the underlying rationale of the method.
