Today we worked hard observing, working within to add and find the difference and to play a game on the 100's chart. I took pieces of the 100's chart out and had them fill in the missing pieces. We talked about how our name tag can be a tool for us to use when adding and subtracting double digit numbers. We just started noticing the patterns on the 100's chart and ways to add and subtract by 1's and 10's. We will continue to work on this throughout the week.
