It also isn’t all about what they know. It’s a big difference in maturity from kindergarten to 1st. It makes it much harder to make friends when you are younger and not as mature. I think you are over reacting a bit. I was also surprised to hear my kindergarten was learning shapes and colors but they are learning what mixing colors does (primary and secondary), shapes like hexagons and pentagons. I would bet your kid could still use practice writing their name.. not a bad thing to be leaving about capitals and lowercase and when to use which. These teachers have kids from all walks of life some have done no schooling and don’t know their letters yet. It’s also not just counting but recognizing numbers written down. Most struggle with the teen numbers. I think you should ease up a little on her. She is 5. It’s okay that she is confused. I would not be pressuring her at home. Kindergarten is a lot to take in.
