Grade(s)

Overview

Students will view a video that describes the relationship between multiplication and division. The video provides several illustrations that demonstrate this relationship. After viewing the video, the students will draw illustrations and corresponding math equations to show their understanding of this mathematical relationship.

This activity results from the ALEX Resource Development Summit.

Derived fact

Knowledge

Students know:

Strategies for finding products and quotients.
How to use multiplication facts in terms of a missing factor to learn division facts.

Skills

Students are able to:

Use strategies based on properties of operations and patterns of multiplication to find products and quotients.
Use efficient multiplication and division strategies based on the numbers in the problems. -Use multiplication facts in terms of a missing factor to learn division facts.

Understanding

Students understand that:

they can use the meaning of the numbers in multiplication and division situations to determine strategies to become fluent with multiplication and division facts.

Learning Objectives

Students will fluently multiply and divide within 100, using the relationship between multiplication and division.

Activity Details

Prior to playing the video, the teacher will instruct students to have a sheet of paper and a pencil. The students should write down the examples from the video that explain the relationship between multiplication and division. These notes will help students complete their task after watching the video.
The teacher should play the video, Multiplication and Division Relationships - Fun Math Videos for Kids 3rd Grade (4:02 minutes).
In the video, the relationship between the math families of 4, 3, and 12, and 3, 5, and 15 are described and illustrated. Instruct students to choose another math fact family to illustrate to show their understanding of this concept.
Students should write the multiplication and division problem associated with the fact family. They should draw an illustration to represent this fact family.

Assessment Strategies

The teacher should review each student's final work product and ensure that each student included:

a correctly completed multiplication equation.
a correctly completed division equation.
a corresponding illustration.

Variation Tips

If needed, the teacher could provide additional demonstrations of the relationship between multiplication and division prior to having students complete the work individually. Alternatively, the teacher could allow students to practice the skill in partners or small groups. The teacher could assign the class or each student a fact family to illustrate for the final product, rather than allowing students to select their own fact family.

Background / Preparation

The teacher will need internet access and video-playing capabilities. Students will need paper and pencil to complete the activity.
