I cannot believe that other 3-yr-olds do not understand 1-to-1 counting -- is that really true? When are kids supposed to know how to do that? I read something that they expect kids to count 10 objects after completing kindergarten -- is that accurate?
I feel like this often! Ds is in the class equivalent to your K (we in the UK) - but the kids are 4-5. The last week before the holidays they 'introduced addition and subtraction as taking one away or adding one more'; they were singing '10 green bottles', doing things like getting one more car etc, in the 3-4 class they were working on recognising numbers 1-10 and 1:1 counting.
I'm always shocked by the newsletter because my just-turned DD2 can do the 3-4 stuff and my DS4 seems way beyond his class.
Your DD does sound GT from what I've read on here. My DS does the 'i can't do it thing' too.
