I’m working on an activity that requires students to use powers and division to write three expressions for 10^5. I’ve been exploring the topics in here and have compiled a few different responses, but I don’t understand the graph enough on how to have it check the responses to get a check mark on the teacher dashboard.

I want to make sure they write a quotient and not a product which is why I don’t want to use countNumberUsage.

To force a certain form, like a fraction, you will want to use Patterns. Here is an example of how you can do that (you don’t need a graph component at all in this case).
