DD8 is in 3rd grade and stays in her class for math, although she does 4th/5th challenge math at home.
Our oldest two are quite different in their approach to school. DS desires new input and DD is happy to have time with friends. DS craves extra challenge and his peers have always recognized this. When he leaves the class it has never had any negative social implications. However, with DD, she resists any in-school challenge, as peer relationships are much trickier. She, too, is the youngest in her grade and I readily admit that when she does anything different it tends to create tension. I don't want to hijack the thread, so I should stop typing!
