I love how math topics just come up naturally in our classroom. The other day we were doing one of our daily math pages as a warm up to our math time. It was this particular one from my April Morning Math and when we got to the Comparing section we came to 10=10.
1.OA.D.7 Understand the meaning of the equal sign, and determine if equations involving addition and subtraction are true or false. For example, which of the following equations are true and which are false? 6 = 6, 7 = 8 – 1, 5 + 2 = 2 + 5, 4 + 1 = 5 + 2.
I guess I am a little ahead of the game, but when those moments come up, you just can't let them pass by. We did another one today and here's what we did. I love that my smarties are beginning to compensate without me even teaching the strategy!!! Of course, we had to name it and refer to it by name every time someone uses it in the near future. Can't wait to see what they can do next- I think I will give them equations with one addend missing on one side like this: 3+4 = ? + 2.
