Hi Penny!
We used “Noble Knights of Knowledge” for awhile but sadly it didn’t work for us. It required alot of parental prep time, creativity on my part, and ongoing interaction during the entire lesson. Also, my ds became bored with the repetive story games after awhile, though at first the colorful boards, gems, and animals were lots of fun. This might be good to use as a supplement to your current math curriculum if your dc enjoy lingering long with math manipulatives and you enjoy being creative. I do wish this would have worked for us and hopefully you’ll get some positive feedback.
Blessings to you & yours! Heather
