Finding & Correcting Mistakes – Whole Number Operations
Each of the problems has been solved, but the solutions contain mistakes! Students find the mistakes, and then explain and correct them.
- answering the wrong question
- making an arithmetic error
- choosing the wrong operation
- using one operation when two is needed to solve the problem
- labeling the answer incorrectly
- using the extra information in the solution.
8 problems include whole numbers and all operations.
Use during guided math, during tutoring or intervention, with small groups, or in centers.
This activity includes clear and concise teacher directions, a detailed answer key, and conversation starters that give students what they need to have meaningful academic discussions.
