I thought you might like to know which reviews we are continuing to use.
I am not convinced that we will finish the course before our time runs out and we've had vacation and some health issues, meaning we've missed a few weeks and therefore will need to do some back tracking.
Sunya (a math game) and Flipstir (a logic game).
Of the two my son loved Sunya and often plays it with his gramma. He finds it an easy game to play, and likes the gramma enjoys playing it with him. Between Sunya and Chess, math is covered when he goes and visits (and needs to do some school too).
I, on the other hand, had a distinct fondness for Flipstir. I remember getting frustrated by it and having my international student come along and sort it out and even give a hint about solving it. It was an excellent smile for us.
