7 yr old son is challenged by these problems. I can see he's really thinking about what he is reading. Much more fun than memorizing tables. I think we'll end up doing each level as he progresses.

All of The Perplexors series are absolutely wonderful. My kiddos love them and find them so enjoyable that they look forward to receiving new levels as though they were receiving games!

We love these! They are just the right amount of challenge.
