I’m a homeschool teacher of a nine-year-old, and we sometimes have one-on-one ‘number talks’ (a.k.a. 'math talks') similar to the activity used in primary school classrooms.
Part of this process involves writing down the thinking process used to solve a particular problem. For example, my child might explain the steps they used to solve 5 x 25 in their head. In turn, I write the process down on paper as they watch.
Is there a standard notation / recording technique for writing down thinking processes used in number talks? Or is there a resource that may provide some helpful ideas in this regard?
In my brief experience, I’m finding that my written diagrams or notations are not ideal. Admittedly, I will draw operators, numerals, and arrows on-the-fly, and they don’t always clearly communicate the process, especially when looking at them a few days later.
I’m particularly concerned about this because one of my longer term goals of these number talks is to encourage good written communication about math, and I’m not always being a good role model.
