Really? Yikes, I'm glad I asked. I guess I can kind of see that.

I already give them more, because I have to keep them busy for 20 minutes and they finish their assigned work in like.. 4. They are given one worksheet.

Lately I've been having them make up their own addition problems and then we all solve them together as a group.

But it feels very ineffective.

I wonder if I can ask her if "we can come up with some bonus problems" to give them if they finish and get restless. If she likes the idea, then offer to create them?
