Yes!! DD is also freaked out by killing trees and gives this as a reason to fit it all on one page. And yes, if I do a problem alongside her, I write down like 3x as much. And now I have a 9yo doing the same thing. (me and his teacher both: "Where is your work?" DS: "What work?")

Ds7 puts a laminator sheet on his workbook and does calculations in the blank space or on top of pictures or other problems.

It doesn't smear?
