“new math” representation

[Julie Sumwalt]

Are there ways to transcribe non-traditional multiplication, such as the box method, lattice multiplication, and drawing lines (like in Japan)? I don't have any concrete examples yet.

Hi Julie.

I am not aware of these methods. If you can send an image later, we can brainstorm approaches.

I'm guessing the box method would be done as a table. I think the stick method would have to be done as a tactile graphic. I've attached a Word document with three images pasted into it.

The box method does lend itself well to a modified table. I would align everything to the left. See attached brf.

I think the lattice method would be most clear as a tactile diagram. I would use thinner lines for the diagonals. It will be pretty big if you include numeric indicators. See what you think about not using NIs. But those little 1's in the corners will be a challenge. I don't really understand the lattice method. Are there hints to how it is read?

The stick method looks to me like something that would be done with actual sticks. I am not a TG expert, so I can't make suggestions here but it seems to me that it would be pretty confusing as a tactile graphic. I know you are good at that, so I am leaving it in your hands, Julie. My best suggestion is to follow print as best you can and describe the colors in a transcriber's note.

This looks like a very interesting project.

Thanks for the input and ideas! I had to look online to find out how these methods work. I will do my best to make it clear.
