In this activity, we will learn about multiplying by 3.
To multiply by three, we can use repeated addition.
Here are 3 cats in a group.
Let's think about what happens if we have four groups of 3 cats and we want to find the total!
We could count the cats one by one, but this would take a while.
Instead, let's use repeated addition to show the total.
4 groups of 3 looks like this as repeated addition:
3 + 3 + 3 + 3 = 12
There are 12 cats in total!
Now let's try an example of multiplying by 3, using repeated addition.
Example
There are 9 pots.
Each pot has 3 flowers.
We want to work out how many flowers there are in total.
What is 9 times 3?
Answer
In total, there are 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 = 27 flowers.
What is 3 times 9?
3 × 9 = 27
9 × 3 = 27
Now that you understand repeated addition, let's try some questions.
