Our pull out program is basically a fall project and a spring project. The fall project was about Wind Power and was really elaborate. DS couldn't have cared less about it. He saw it as just more work. Between you and me - if they would have asked him to do a presentation over Greek Mythology he would have been all over it. His spring project is a little more interesting but is still just more work. The GT group also runs the school store on Thursday mornings. While DS does enjoy this and there are real world applications for it running the store doesn't solve our boredom with math.
To complicate matters, DS has a late September bday and the cutoff for enrollment in kindergarten was 9/1. So he is an "old" 4th grader. Back then I really waffled on pushing to enroll him earlier and then decided it would be better to wait and let him be an older kid since boys mature slower. I sometimes regret that decision.
