## Read the story

Theo buys a backpack for 38 dollars and shoes for 61 dollars.

About how much is that? We round to the nearest ten.

38 is closer to 40. 61 is closer to 60.

40 plus 60 is 100. That's about 100 dollars.

**A jacket costs 49 dollars, and pants cost 32 dollars. About how much is that?**

## Answer and working

Correct! 49 becomes 50, and 32 becomes 30. That's about 80 dollars.

`50 + 30 = 80`
