In this lesson plan, which is adaptable for grades 3 to 5, students use BrainPOP resources to explore the relationship between multiplication and division. Students will complete a variety of activities to help them understand these operations in real-world contexts.
- Explore the relationship between multiplication and division.
Preparation:Use this lesson as an introduction to a unit on division. Be sure to preview the movie on division to plan talking and pause points.
- Have each student take and submit the Division Quiz (using clickers, computers, or paper/pencil) as a pre-assessment of their understanding of division. Use their scores as one measure to differentiate instruction throughout the unit.
- Ask students, “How is multiplication related to division?”
- Pose the following problem: How many boxes of crayons, with 8 crayons in each box, can be made with 32 crayons? Guide students with questions such as: How many 8s are in 32? 8 times what number is 32? How much is 32 divided by 8?
- Point out that in the division fact 32 / 8 = 4, the number 32 is the dividend, 8 is the divisor, and 4 is the quotient. Also, discuss the multiplication/division fact family: 4 * 8 = 32, 8 * 4 = 32, 32/4 = 8, and 32/8 = 4.
- Project the Star Diagram Activity Page for the class to see. Complete the activity page as a class. Type the students’ responses directly onto the page.
- Tell students you are going to watch the BrainPOP movie on division twice. The first time students should note any comments/questions. Prior to the second viewing, instruct students to fill in Vocabulary page as they watch the video.
- Discuss any comments, questions, and review vocabulary. Have students make any necessary corrections.
- Ask students to complete the Fill in the Chart Division Page. Remind them to reference their multiplication/division fact families, as this will make solving division problems much easier.
- Inquire, "Now, how do you think multiplication and division are related? Have your thoughts changed?" Discuss.
