Dividing with Repeated Subtraction Adventure

Dividing with Repeated Subtraction Adventure

Learning Objective

Understand how to divide using repeated subtraction and solve division problems.

What do you already know about sharing things equally?

Introduction to Division

Division is splitting a number into equal parts. We use it to share things equally or find out how many groups of a certain size are in a number.

Repeated Subtraction

We can use repeated subtraction to divide. For example, if we have 12 candies and want to share them equally with 3 friends, we can subtract 3 from 12 repeatedly until we can't anymore.

How Many Times?

In our example, we subtracted 3 from 12 three times. This means 12 ÷ 3 = 4. Each friend gets 4 candies.

Division Symbol

The division symbol looks like this: ÷. It shows that we are dividing numbers.

Challenge Question 1

If there are 20 cookies and 5 friends want to share them equally, how many cookies will each friend get?

Challenge Question 2

If there are 15 pencils and they need to be divided into 3 equal groups, how many pencils will be in each group?

Task to Complete

Create your own division story problem using repeated subtraction and share it with the class.

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.
