My 5 year old listens to everything we do here at home and picks up on lots of information...faster than my other two did. Anyway, becasue of that, the kindergarten Saxon Math was too beneath him and I started him in the 1st grade book...which, overall is just right for him, except his writing skills are not where his brain is. Should I be concerned if he can't write many of his answers small enough to fit in the spaces provided, that he still makes many of his numbers (and letters too, although that doesn't affect math) backwards.? He is totally understanding the acedemic part of it..and sometimes, he is even getting bored with the repetition...but we deal with that. What do you guys think?
