Suggestions for mathematical diagrams that you might want to assess a student's interaction with, please. Interaction could be moving objects in the diagram, typing a number or formula in a box, or ticking checkboxes.

So far I've got...

Placing objects on a Venn diagram: drag a point to an appropriate position, or tick boxes representing membership in each of the sets.

Move a point to given coordinates: drag a point on a grid, or type in Cartesian coordinates
