Draw a tick mark near the bottom of the number line.

To the right, label it 100 = 1 hundred.

What is 1 more hundred? 2 hundredsDraw a tick mark near the top of the number line. To the right, label 200 = 2 hundreds.

What number is halfway between 100 and 200? 150! In unit form, what is the number halfway between 1 hundred and 2 hundreds? 1 hundred 5 tens.

Estimate to draw a tick mark halfway between 100 and 200. Label it 150 = 1 hundred 5 tens.
