Hmm, great input! I read another thread about CLE Math where mom dropped booklets 1 and 10 because they were review. Also, we already did fractions in another program.
So, since we do math year round, maybe we could do books 2-9 of CLE 6, skipping a large portion of the fractions sections, and THEN do the more challenging Chalkdust once the mechanics are thoroughly drilled down.
I’m not sure if that’s wise or redundant. In any case, he certainly needs to get more consistent and quicker at mechanics.
