Dear Shel, You sound like a very good mom who only wants the best for her child as you try to make sure everything is the way it should be in kindergarten. You have every right to express your concerns respectfully to the teacher and administration as far as clarification of the curriculum as well as the match to your child's performance. And you are entitled to your feelings. I assume your daughter is in kindergarten. I can certainly understand as a preschool teacher your wish for her teacher to know how capable YOU have found your daughter to be.
Teachers are usually pretty good at evaluating a child's progress during the year.
I'm assuming she has no problem in these areas. If your daughter does finish an assignment faster than the rest of the class, you can ask the teacher how she would handle that. A child needs a chance to think on her own, to imagine, to create something to keep her mind busy. Boredom is not necessarily a bad thing. That means that she gives you unsolicited information that she does not like school.
