YMMV, but around here I don't think they *do* assess children first entering school, and certainly not for whether they can do multiplication. My experience was - ah, actually explained in
the first thread I ever started, but the short version is that DS's teacher, despite noticing his advanced reading on Day 1, didn't notice his maths for more than half a term, until I send in a note.
Still, my DS was probably difficult to spot at that point, and it sounds as though your DD is somewhat similar. He'd grab on to and be fascinated by advanced concepts, but he'd also make mistakes in, or be unwilling to try, apparently simpler problems; I'm not sure he'd have assessed that well, and on the whole I'm glad I didn't push it at the very beginning. I think with hindsight I'd have contacted his teacher a *bit* earlier, since as it was DS had been complaining about maths being boring for some weeks before he got any differentiation. I vote a month ;-) Obviously if the teacher asks, or gives you an obvious opportunity to talk about your DD, before then, go for it then!
