I have just taken over a new class in Year 5. They've had three teachers so far this year. Just before half term I got the leaving teacher to get them to sit some maths and writing papers. Writing is reasonable, and the levels are appropriate to the info i've got, but the maths is WAY out, and their papers are horrifying. I'm meant to be moving onto C2 with them, but from the papers I think fully 3/4 of the class don't get multipication, division, place value, fractions, and I could go on. Yet their levels suggest they should. It's not just a bad paper either, i've looked through their books this morning in school and their work is very gappy.
Any advice at all welcome! Currently, i'm thinking I should just plan to go back to basics for the first 4 weeks back. Oh, and there isn't another colleague to plan with, long-term sick. Thankyou, in panic!
