my kinesthetic learner has only ever been able to learn math from MathUSee. I resisted getting it. I didn't like the way the manipulatives felt, I didn't like the U in the name...I hate intentional misspellings
and I didn't want to support that. I had to get over it, because it was what worked best.
making letters in a tray of salt or sand, making letters out of playdough, stuff like that works. there is a kind of flash cards that my dd's montessori school used called a kinesthetic alphabet. you might see if a google search turns it up. it would be cheap b/c you could just print it out at home and make up the cards yourself.
