As a school solution, we do not provide students with printed worksheets, but instead provide laminated white paper. We write (or print) the questions on them and they can be wiped clean. This however, introduces an issue with parents, as they often would like to know how their child is doing. They would have to ask us instead of asking their own child (which takes away some of trust building with your child, maybe?).

You can now draw on phones and tablets by clicking on the worksheet, quite useful while on the go with kids or to save some paper.

Well done!

Is there a trick to getting back to the grid once you've gone into a sheet? Short of a refresh, that is, which erases the work.

I was thinking of locking the UI to keep kids focused on finishing the worksheet before they ask for help to get a new one. But I agree it's currently hard to get back to get grid, I'll add support for navigating back to the grid to using the back button.
