Question Video: Representing Hundreds Using Place Value Models Mathematics • 2nd Grade

Video Transcript

This place value block is 100. How can we show 300?

In this question, we’re introduced to a place value block. We already know what ones and tens blocks look like. We’re told that this blue block is worth 100. And we can see this because it’s the same as just pushing 10 tens blocks together. 10 10s are the same as 100 ⁠— 10, 20, 30, 40, 50, 60, 70, 80, 90, 100. Now to show 100, we just skip counted in tens. But our question asks us to show 300. So we’re going to need to skip count in hundreds ⁠— 100, 200, 300. We know that one blue place value block is worth 100. And so to show the number 300, we need to use three of these hundreds place value blocks. Three 100s are the same as the number 300.
