In math today first graders played a game called Roll and Record. It involved finding the sum of 2 numbers and recording it on a chart. The game ended when one of the numbers reached the top of it's column. At our closing discussion we noticed that certain numbers were "popular winners". We discussed why 7, for example, was a frequent winner. The students thought that the numbers who had more possible combinations had a better chance of being rolled. Great math thinking!!
We also had a great discussion about the concept of "true equations". Volunteers held up some numbers and symbols and they moved around to make true equations.
We then looked at the equations that we came up with and did some algebraic thinking!! Wow! These first graders are wonderful math thinkers!!
