Round About

I’m 9 years old . . . well almost. I’ll be 9 next month. That means I’m just about 9.

Just about means close to or almost.

These are words and phrases we use every day.

It is just about 3:00.

Look at this cool skateboard. It costs close to $50.

We can decide what is just about or close to or almost by using a number line.

11 12 13 14 15 16 17 18 19 20

Look at the number line, then click the closest ten.

14 is closer to 10 or 20

17 is just about 10 or 20

15 is right in the middle between 10 and 20.

* Rule - 5 goes up.*

15 has a 5 so we say it is closer to 20.
