Understanding Inverse Operations WORKSHEET
Suitable for Grades: 3rd Grade
CCSS: 3.OA.A.4, 3.OA.C.7
CCSS Description: Determine the unknown whole number in a multiplication or division equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 × ? = 48, 5 = � ÷ 3, 6 × 6 = ?.
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 products of two one-digit numbers.

Understanding Inverse Operations WORKSHEET DESCRIPTION
Understanding how to select and use inverse operations is essential in order for students to use function machines, solve linear equations, and answer many other problems. Familiarize your learners with the basics of this principle with this colorful worksheet.
In section A, students will simply select the correct inverse operation to all four operations before completing a matching activity in section B. Here, students will match six mathematical statements with their correct inverse operations.
Next, in section C, students are faced with another six mathematical statements. This time, they must write the correct inverse operation of each themselves. Answers may vary here, which provides a great classroom discussion point.
