Copying Combination of Previous Sketches


I am working on an activity where students will answer a question and then make a sketch. Then, they will answer another question and add more onto that original sketch. Then, they will answer yet another question, and add once again onto the past 2 sketches. Ideally I need this to work for 10 in a row.

Right now, I am able to copy previous for the sketch without issues, but once I copy previous for the third sketch (copying sketch2), it only shows what I drew on it for that sketch, not the first one AND sketch 2. Is there a way to do this? Where you can add more and more to the screen and copy it all each time and not just what you added on the last screen?

Sorry if this is confusing, it was tricky to explain!

Thank you for any and all suggestions :slight_smile:

Daniel’s got you covered on the code. This is an activity I wrote so you can see it in action: Math Mystery: Inequalities • Activity Builder by Desmos The sketch carryover happens on the odd screens from 3-21

This worked perfectly! Thank you so much! And that’s funny, mine was also for a Mystery :slight_smile:
