Later, as we worked in our workbooks, I found that some kids were still confused. They did not have enough schema with the Hundreds Board to visualize where and how to find the answer. I did not want them to always rely on counting. Instead, we reviewed the vocabulary more and less. Then, we talked about what happened to the digits if it was 1 more or 10 less. Then, on the spur of the moment, I quickly drew a Place Value Robot, as I called him. We pretended to be the robot. The beginning digit was on our tummy. If we needed 10 more, we touched our toes. This reminded us we needed to look down on the Hundreds Board. If it was 10 less, we touched our heads. One less was to the left and one more was on the right. Get it?
