Add Up the Tens

When you divide by ten, you can think of it as adding up the tens.

Here’s how.

10 + 10 + 10 = 30

Since there are three tens, 10 goes into 30 three times. So, the answer is 3!

Group the Tens

You can also think of division as putting things in groups.

  • Do you have a collection?

Imagine you have 40 stickers or stuffed animals. Now, divide those 40 items into ten groups.

  • How many are in each group?

That's your answer!

When you divide 40 by 10, you’re finding out how many tens fit into 40.

Using objects, it looks something like this.

four groups of ten

Each circled group has ten squares in it. If you count the groups, there are four of them.

That means 10 goes into 40 four times. So the answer is 4!

You can also write the expression with symbols. This is fun and saves time!
