For all of their hatred of numbers in their various forms, kids really struggle with graphing. Something I tried this year, and will expand on next year, is to just have them copy graphed lines off of my slide onto their xeroxed worksheet of grids.
As I went around, I gave a running count of what percentage of the class copied the line correctly. I pointedly ignored their queries of whether they were right or not. They had to go to their friends, and figure out what was up.
There were no numbers, no calculations. But they spent the whole period engaged and figuring out how to look at a line and its relation to the coordinate axes.
