Apologies if this is long, but don't want to drip feed. Background: dd has an alternate teacher one day a week. Right from the start, she's found the work from this teacher very easy and pretty much invariably comes home complaining about being bored stiff all day.
Teacher is new to the school, and so back in September, my feeling was she was just getting the measure of the pupils, and easing in gently. Then after half term it was nearly Christmas, then it was almost half term, you know how it goes.
Fast forward to now, and dd is now really not wanting to go to school on a Wednesday, it sounds to me from reading between the lines that she's messing around and getting in trouble (this wouldn't be at all out of character, shall we say), etc etc.
Again only from what dd says, but it sounds like the teacher isn't doing any differentiation at all, the whole class (yr 5 & yr 6) are doing the same work. The example she gave today was spending the entire morning doing addition/subtraction involving negative nos. (so -9 + 12) and ordering nos including negatives. Maths is definitely dd's 'thing' and whilst she may have been exaggerating when she said she was doing this type of sums in yr 2, she's probably not overstating the case greatly.
So, the question is, given we're now getting towards Easter, would you try (continue) to persuade dd to put up and shut up, or would you go in and speak tactfully to the class teacher?
