What number could the point on the number line represent? Record an estimate that is:

Look at the point for 128 on the number line.Name two multiples of 10 that are the closest to 128.

Which of the two is the nearest multiple of 10?

Is 349 closer to 300 or 400?

Is 349 closer to 340 or 350?

Is 712 closer to 700 or 800?

Is 712 closer to 710 or 720?

Is 568 closer to 500 or 600?

Is 568 closer to 560 or 570?

Without locating a given number on a number line, how did you decide the nearest multiple of 100?
