I know it has been a great day when after a lesson someone says with a huge smile on their face, "thanks for letting us do that!" (thanks Righley for making my day). We are learning about odd and even this week. Students have worked to think about numbers as a set of something (not just an abstract symbol). Today we played a little musical math by checking to see if our numbers were odd or even. I wished I had filmed more of the lesson before the activity. I hope you enjoy this as much as I did!
