Here are some dice.

What do you notice about these dice?

You may have noticed that there are 4 dice and they all show the number 3.

What is 3 + 3 + 3 + 3?

There is more than one way to find the right answer.

You could double the first two, then double them again.Or you could count up in 3s.

Did you get the answer 12?

Here are some cubes.

Can you see a pattern?

The numbers are increasing.

3, 6, 9, 12

The numbers are increasing by 3 each time.

3 + 3 + 3 + 3 = 12

Here is an array.

We can count in 3s from top to bottom.

Or from left to right.

This is what counting up in 3s looks like on a number line.

Can you see a pattern? What do you notice?

Here is another way to count in 3s.

Put your hands out in front of you, palms facing up.

Starting with your left thumb, count up in 3s.

After 30 what are the next 3 multiples of 3?

Let’s count in 3s:

3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39

Can you continue the pattern?

How far can you go?

Can you count back in 3s from 30?
