Why a 120 Chart?

What is the point of 120 chart versus a 100 chart? You may think it's something to do with those times twelve multiplication facts, but it's actually something quite a bit more basic.

We practice counting by ones and skip counting numbers and many basic arithmetic skills solidly in the realm of two digit numbers. And for exactly this reason, when many kids get to a hundred, they're not sure where to go next. If you ask a first grade or second grade student what number follows one hundred, you'll occaisonally be surprised at the answer... I've gotten 110, 102, 200, and other values that would leave you exasperated.

A 120 chart is a perfect way to address this. By seeing the sequence of numbers on a 120 chart, a student has the opportunity to develop a mental framework for numbers that follow 100 and to start getting the sense that those place value concepts used to count ones and tens just carry over into hundreds as well. A 120 chart is just long enough to push kids over that one small hurdle, and it's part of the reason the Common Core standards have encouraged fact practice up through 120.
