Exploring Multiplication and Division

Exploring Multiplication and Division

Learning Objective

Understand the connection between multiplication and division and use reasoning to solve problems.

What do you already know about multiplication and division?

What is Multiplication?

Multiplication is combining equal groups to find the total amount. For example, 3 groups of 4 is the same as 3 x 4.

What is Division?

Division is sharing or grouping a number into equal parts. It is the opposite of multiplication.

Linking Multiplication and Division

Multiplication and division are related. Knowing the multiplication fact 3 x 4 = 12 helps us to find the division fact 12 ÷ 4 = 3.

Open-Ended Question 1

If 5 x 3 = 15, what could the division fact be? How did you figure it out?

Open-Ended Question 2

How can you use what you know about multiplication to solve a division problem?

Problem-Solving Activity

Provide word problems involving multiplication and division for students to solve in pairs or small groups.

Review and Reflection

Ask students to reflect on how they used reasoning to solve multiplication and division problems.

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
