Yes ColinsMum, you are right she does have an opinion and the opinion is that she absolutely does not want to do math over summer break. Do you think it is a problem that she does not know something like, 12-8 by rote? I don't know... she is ahead of the curve conceptually (which I guess should not surprise me since that is, in fact, what they emphasize at her school). I guess I just worry that as the concepts get harder things will get exponentially harder without a solid grasp on basic arithmetic.
Yesterday I made her do 30 minutes of math and 30 minutes of piano practice, which makes me either the best mom ever or the worst mom ever - depending on your perspective.
