Hm - didn't get to playing the games until near bedtime - and Delta just wouldn't sit still. He also was doing worse at blending to make the word - and seems to have forgotten the sound "T" makes, even with repetition. Then Echo was getting upset because she couldn't sit where she wanted (in the way) - although she was doing good with her words.... So I ended up stopping it early as I was getting frustrated.
I've notice that the blocks game seems to make them have to figure out the word a bit more (ie, they have the card, and have to read it and say what it says...) where-as the ledges game has them more pick out the word from the various words after I say it.... We haven't played blocks for a while, and that might have been more the problem.
Will have to play blocks with them seperately, and backtrack a bit for Delta to get the T sound in really good.
