Class 3 maths teacher has banned erasers, and my neat son hates his notebook now
From this term the maths teacher wants mistakes crossed out with a single line, no rubbing out. I can see the reasoning; I ask my own students to keep their working for much the same reason. My son, though, would rather start a page again than leave a crossing on it. Last night he tore out a page and redid it twice, which took longer than the sums. Has anyone's child had this rule? Did they settle into it, and is there something I can say at home that doesn't undermine the teacher?
