BenjaminL thanks for your post. I do something similar with daughter, age 10. She goes to regular school but we work on math 10-20 minutes in the morning starting about a year ago. It doesn't seem like a lot but she has gone far in that time. Based on your post, we just started reading the AOPS pre-algebra book and she likes it a lot. I wondered if you could catch us up on what he & you have worked on in math in the last 4 years? Thanks.
