My child used to use Kumon. It was a fair program. However, he found it repetitive and boring after a while. Since my 2nd grade child is gifted in math but has a short attention span, we always want to find a fun math program to keep his curious interests. His teacher recommended Beestar to us. We found its GT program (gifted and talented) suits my child better. He enjoys the interesting and challenging problems, especially those visual graphic problems. Beestar has a weekly honor roll that motivates him to work hard and get ahead. It brings a lot of fun to learning. Beestar is online so he can practice anytime at home or even at a hotel while we travel. His exercises are graded instantly. We enjoy the convenience and flexibility.
