Concept Development

We’ve practiced rounding numbers to the nearest ten. Today let’s find 132 grams rounded to the nearest hundred.

How many hundreds are in 132 grams? 1 hundred

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.

Look at your vertical number line, is 132 more than halfway or less than halfway between 100 and 200?

132 is less than halfway between 1 hundred and 2 hundreds.

132 rounded to the nearest hundred is? 100.

In unit form. : 1 hundred 3 tens 2 ones rounded to the nearest hundred is 1 hundred.
