ashley has made some excellent recommendations already. DD4 is advanced in math and has completed 1st grade level math (on ixl.com) a few months ago and comfortably working on 2nd grade (conceptually knows even higher). She has just started to read but readingeggs.com estimates her reading age at 5.5 (for what it is worth) and she is making progress in leaps and bounds. Her school is not academically focused at all. Her teacher is not providing her challenging material at all. However, DD is very happy. She is partially home-schooled (1.5-2 days a week) so she is able to satisfy her academic curiosity at home. She goes to school to play with her friends, do art and yoga and drama and hands-on projects. I am planning to continue her there for kindergarten later this year. Maybe you can find a similar setup.
