I'm worried DS is getting switched off maths at school as he doesn't seem to be being stretched. When he got this week's homework worksheet out I joked that I thought it would take him three minutes - so he said, "okay", time me, and I did. We didn't reach 30 seconds, and he got it all right. He's in Y3. Is it worth raising with the teacher, or is homework so trivial in the grand scheme of things I should just let it go.
