We received DS10's scores (4th grade) on EXPLORE and they are a bit all over the place (22 in English, 14 in Math). The math curriculum at their school is not very rigorous and he is the type of kid that gets concepts easily but may make computational errors.

We haven't done much enrichment outside of school. Any recommendations for an online program that he can work on over the summer so that he can go a little deeper and develop his math skills? He is asking to learn algebra.

Thanks!
