Reply To: Lesson 4-1: The Stages of Mastery Action

[Angela Clubb]

It’s July so I can’t teach my class but I did have a Number Talk saved in my Drive from my grade 3 class that I can speak to. The question came from the book, “Number Talks” and the question was “39 + 16”. These were the student responses that I received: (below). We were using Lawson’s scale to determine how students were solving mental math problems and their flexibility with numbers. Now I’m wondering if maybe I could have used concrete materials to make the question accessible to all and then I could have also seen how they would have grouped the blocks, etc. to solve (39 red counters, 16 yellow), etc. Some students may have made the leap to multiplicative thinking had we done this instead?
