Good Morning S., When they started all day kindergarten 30 some years ago, our youngest son, learned ABC, numbers, colors, shapes, following directions, interacting with others. Now they do this in preschool. It will probably be more reinforcements of the above, plus writing. They do so much more now with children then they did when our son's were young. We had already mastered letters, numbers, counting, money, colors and shapes etc before either one of them went to school.
Our eldest went half days every day, our youngest went all day every other day. One week three days next week 2 days.
I was also very involved with the boys class's being an aide some days with reading. Going on field trips, supplying goodies for parties.
He will have a good time and have alot of frig drawings to post. I remember Asher (gr son) bring home re-enforcement sheets to practice different things this last year. Tracing, cutting, matching things. He went to school every day half days. Will be 1st grader this year.
God Bless you and yours
K. Nana of 5
