Your daughter is advanced academically. If she's four, I'm assuming she's still in Pre-K, right? (in my state, you have to be five to start Kindergarten or four turning five before 12/31) Yet, she's capable of doing Kindergarten work. Well, at least Kindergarten work in my area.
Every state sets different guidelines and benchmarks for each grade level. In my state, kids learn to read short sentences and short beginner books in Kindergarten. However, I have read other parents on YA say that in their state, Kindergarten is about exploratory play and learning letters, not reading.
Regardless, she's advanced for four. I'm working on my master's in education and I have been a teaching assistant in a Kindergarten classroom for 3 years. In general, we work on this in Kindergarten:
-Letters and Sounds
-Sight words/Color Words
-rhyming
-blending sounds
-Identifying punctuation (ex: period, question mark, comma, exclamation point)
-sounding out words (we emphasize inventive spelling)
-Identifying elements of a story (beginning, middle, end, characters, problem, solution, retelling and sequencing)
-Context clues from pictures in books
-vocabulary enrichment (cross content for science and social studies)
-whole group activities using bubble maps/circle maps/flow maps
-Number identification, sequencing of numbers
-Identifying shapes
-Word problems involving adding/subtracting
-sorting items, graphing items
-comparing and contrasting (quantity, length, size, etc)
-Money (identifying coins and their worth)
-Time (telling time by the hour, identifying parts of the clock)
-Patterns (AB, ABB, AABB, ABC, etc)
-Reading a calendar (identifying the month, the day of week, the numerical date, the year)
-Sequencing the months of the year and days of the week.
-Weather and seasons
-Animals and their habitats
-plants
-farm life (we do this with our unit on fall)
-weight (part of science)
-holidays (Christmas, Hanukkah and Kwanzaa)
-different cultures and culture diversity
There is a little more than what I listed, but I could sit here all day and talk about this.
Anyway, you should not be worried until she gets to Kindergarten and you can size up the curriculum. If this is worrying you, then go onto your state's Department of Education website. By law, the state must publically post the state guidelines for all content areas in all grade levels for public education. My state has one of the highest standards of public education in the country. Although, I work in an inner city area and I know that students in more affluent areas are writing poetry or short stories in Kindergarten.
I hope this helps you! Again, check your state’s standards. There are some states in this country that have horrible standards! Your state might be one. If this is the case, but you can’t afford private school, consider getting your daughter into a public magnet school. The magnet schools usually perform very well.
