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.

 Is 15 closer to 10 or 20 ?

 Rounding to the nearest hundred is done the same way as rounding to the nearest ten.Look at the number line.  Which hundred is closest to the number? 100  110  120  130  140  150  160  170   180  190  200
 Round 140 to Round 182 to Round 126 to

Rounding numbers has made me hungry!

I hope it’s just about time to eat.

I’m close to starving!

YUM!
