DD is 6, just finished K at a private school. She can count to 5, but gets confused on 6-10 and lost beyond that. BUT she can add, subtract, and knows how much each number is (e.g., can just jump 9 spaces on a Monopoly board or pull out a 4 and a 5 Cuisenaire rod to represent 9).
She uses an abacus to help her with addition and subtraction, but can also do it in her head without it.
DH is freaking that she can't count, and I'm a little worried too that it just won't "stick" in her head, but she gets addition and subtraction.
Is this weird or just a stage? Yes, I'm working with her and starting Miquon Orange for the summer, but I'm less concerned than DH and wondering if he's right or overreacting?
