Equal groups

A grade 3 class has 24 students.

The students need to be divided up into equal groups, with no students left out.

How many ways can the class be divided up evenly?

You may wish to use the number line, counters, or another method of your choice to help count and support your thinking!

Let’s explore a Number Line together! Your teacher will show you how to use the Number Line and then you can try using it yourself!

Record your ideas in your notebook or another method of your choice.

Equal groups in the classroom

Let’s think back to the grade 3 class from the Minds On section.

Reflect on how you may have evenly divided up the class and how that could be represented.

4 groups of 6 or 6 groups of 4?

Did you use 4 groups of 6 or 6 groups of 4?

Press ‘Equal Groups’ to reveal how 4 groups of 6 or 6 groups of 4 can be represented.

Equal Groups

$4\times 6=24$

$6\times 4=24$

$24÷4=6$

$24÷6=4$

Therefore, 4, 6, and 24 are a fact family.

12 groups of 2 or 2 groups of 12?

How about 12 groups of 2 or 2 groups of 12?

Complete the missing numbers for this fact family. $12\times 2=24$

For each sentence, select the missing “number” from the drop-down menu.

3 groups of 8 or 8 groups of 3?

Did you find 3 groups of 8 or 8 groups of 3?

Record this fact family.

Press ‘Show Answer’ to reveal the complete fact family.

Tricycles and bicycles

Tricycles have only three wheels each.

Inside a store, there are four tricycles on display, and six bicycles on display in another section of the store. Which section has more wheels?

Use the numbers in the problem to help you explain how multiplication and division are related and how you can use that relationship to show if expressions are equal or not.

You may wish to use tools like the hundred chart or counters, like wooden shapes or small items to help count and support your thinking!

Let’s explore a Hundred Chart together! Your teacher will show you how to use the Hundred Chart and then you can try using it yourself!
