Where would you put them on using a murderous maths scale - those aren't really textbooks, and the level of math seems to vary between late elem/early ms type. DS loves them. And DS 6 is the type who loves learning the theoretical but still working on the facts that school is sending home. And he has just soaked up the mm theory, so when he is doing those worksheets you mention and finds them so simple because he already understands about x and equations, etc. So i haven't been sure where to have him go next, would you recommend this, or would you consider it a more formal textbook replacement?
Thanks,
