Cindy of "Apple Stars" categorizes Right Brained learners in to types.
All of my boys seem to have some "builder" type traits. Here are some wonderful distractions that they have enjoyed and that I think other builder/visual learners would like.
Fractiles, magnetic tiles that fit together on a magnetic board to make beautiful, interesting, and mathematical patterns. Art worthy, but has small edible-sized tiles.
We bought Zome Tool before we even had children. It is rods and balls that fit together to make shapes intriguing and, alas, fragile. Warning, these are addictive. You'll need more than one set if you want your kids to share with you. Also, it has small parts, so if your toddler or dog eats small bits, you'll want to be careful.
Puzzellations, magnetic backed foam shapes that tile to make patterns.
LEGO Create-it, a board game that apparently isn't being made anymore, so now I'll describe it and you can decide if it's worth making it. There are several cards with parts illustrated and instructions to make a small vehicle. Each person gets a card. Turns are taken and dice rolled to move around a board and determine number (if any) and color of lego pieces that make be acquired each turn. When you have all your parts, build! Hmm.... never mind, just give the kids some dice and the LEGOs and see what happens.
Blokus, tiles shaped a little like pentominos. This is fun played according to the rules, with your own made up rules, or just to make pretty designs.
Tessera, the perpetual puzzle, another one we got to play with before the kids grew into them. Our set is sturdy and elegant. I wish we'd bought more. With 3 kids we don't have enough for everyone to use at once, and I haven't seen any exactly like them for several years.
And, on the anti-recommend list is a recent thrift store find, Lost in a Jigsaw II. This is a 515 piece jigsaw puzzle with every piece fitting every other piece. AND the picture is such that it can be put together wrong and still look fine from a distance! We are ripping out our hair. My eyeballs are bleeding. I think I'll regift it to a puzzle loving in-law. :-D
