Find the mistake with one- and two-step problems.
All the problems are worked, but they are all wrong! Students find and correct the mistakes to solve the problems. Errors include:
- making an arithmetic error
- choosing the wrong operation
- using only one operation when more than one operation is needed
- labeling the answer incorrectly
8 (incorrectly worked) problems to solve and a recording sheet.
Use in small groups, during guided math, during tutoring or intervention, and in centers.
This activity includes clear and concise teacher directions, problems on cards, a recording sheet, and conversation starters that give students what they need to have meaningful academic discussions.

Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g., knowing that 8 × 5 = 40, one knows 40 ÷ 5 = 8) or properties of operations. By the end of Grade 3, know from memory all pr...
Solve two-step word problems using the four operations. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including roundi...
Fluently add and subtract within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction.
Multiply one-digit whole numbers by multiples of 10 in the range 10-90 (e.g., 9 × 80, 5 × 60) using strategies based on place value and properties of operations.
TeachTransform creates fun math activities that get students involved in real math. We bring decades of education experience to the task, and we believe that students learn best when teachers and students are having fun.
