Question about Sketching a Graph and Checking with Button

I would like students to only be able to check their sketch using an action button after they have attempted a sketch. Is this possible?

Thanks for any help!

For the action button, something like this could work for your first slide:

disabled: when graph1.sketch.totalStrokeLength<5 true otherwise false

You can set the totalStrokeLength to something you prefer - it’s measured based on the number of units in the grid.

Thank you! That was exactly what I was looking for.
