PDF | 9 pages|Grades: 3 - 4

Find the mistakes in the solutions for the problems provided.

Each of the problems has been solved, but the solutions contain mistakes! Students find the mistakes, and then explain and correct them. Errors include:

• making an arithmetic error
• choosing the wrong operation
• using one operation when two is needed to solve the problem
• 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.

#### Common Core Curriculum alignment

• CCSS.MATH.CONTENT.3.OA.A.3

Use multiplication and division within 100 to solve word problems in situations involving equal groups, arrays, and measurement quantities, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.

• CCSS.MATH.CONTENT.3.OA.B.5

Apply properties of operations as strategies to multiply and divide.2 Examples: If 6 × 4 = 24 is known, then 4 × 6 = 24 is also known. (Commutative property of multiplication.) 3 × 5 × 2 can be found by 3 × 5 = 15, then 15 × 2 = 30, or by 5 × ...

• CCSS.MATH.CONTENT.3.OA.C.7

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...

• CCSS.MATH.CONTENT.3.OA.D.8

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...

• CCSS.MATH.CONTENT.3.NBT.A.2

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.
