Looking for suggestions on software that students could use to draw math equations on a WACOM tablet or tablet computer and include the equations in the submissions for a math assignment. What would be cool is to have a student click an LTI button in an assignment and open/embed an object in the assignment page that they can edit/draw on with the tablet. Then they'd close that page (or multiple pages) and submit the assignment. We're looking for this for math assignments in departments that teach quantitative topics. Any ideas?
