Thanks lucounu. I'll look into those, they sound fun. On the topic of reading does anyone have any suggestions for non-fiction/science books that are written around a third grade level but that are fiarly comprehensive/ in-depth/ accurate? Connor LOVES science but we have to walk a line between the information being advanced enough while keeping the reading level at the third grade level. His science comprehension is wuite high (he knows concepts that my middle and high school SS's are just learning)but gets lost if the writing is too technical/dry.
