A friend recently explained to me how her daughter was showing her thinking for adding on a hundred chart, and I was intrigued. I asked her to send me a picture:
I love how the kids are showing their hundred chart thinking without the actual hundred chart. Notice also that they are apparently required to show their thinking two ways–in this case with an open number line and the partial hundred chart.
I made a little freebie that can be used to practice this type of recording. But as you see in the picture above, a simple word problem and a composition book work wonders!
