I have heard these books be recommended several times - just had a look on Amazon, and they are pretty pricey - so I thought I'd better check and see if they would be suitable for my son before buying. He is 6 - almost 7 - is very mathy - has not been identified as gifted, but does go to gifted pullout for math enrichment (they use "Hands on Equations"). I'm looking for something to keep him busy during the fast approaching summer vacation. If you think the LOF books would work for him - which one would you recommend ? Thanks so much !
