Last spring, as we were working through the following Number talk 72 – 38, students offered the solutions of 46, 44, 34 and after writing them down I turned around to face the class and was about to pose a question to the class when a student said, “I know what question you are going to ask.”
I have been using number talks in my elementary math classroom for seven years now and I thoroughly enjoy them and so do my students. The amount of growth in number sense, discourse and confidence in my students has been attributed to the use of Number Talks and the tweak I made six years ago.
I came across Ben Orlin’s blog post dealing with paper and pencil games. I was immediately drawn in trying them at home and quickly introduced them to my grade three students in our daily online math meet ups.
Students enjoyed them thoroughly leaving them wanting more and that is when my search began.
