Are there any books for younger kids where they don’t have to write out all of the problems?

Yes there are. Saxon Math has a line of workbooks called Adaptations. They go along with Intermediate 3 and Intermediate 4 textbooks. It includes the problems on the page so kids don’t have to rewrite the problem. We’ve surveyed our parents. Some like it and others do not. The primary reason people like it is that their kiddos don’t have to rewrite the problems. The primary reason people dislike it is because the workbooks also give hints on how to do the problems that can sometimes give away the answers.
