Just curious, as we are finishing a few of their books and I was thinking of getting something different to change things up a bit. This year, my almost-10 year old has used Balance Math Level 1, Dr. Funster's Word Benders and Spelling DooRiddles, B1? Ds1, age 7, has been using Spelling DooRiddles A1. I think they're fantastic!
I've been looking at Balance Benders (beginning) and maybe Word Roots.
I'm also interested in suggestions for a 4-5 year old who wants to do "homework" when his older siblings work on things.
