In fact, I'm certain my DS was the only entering reader in his K class. DD had one other for sure--possibly one or two more had early decoding skills, but I don't know.

By year's end, they are expected to know all letters, addition and subtraction to 10 (maybe to 20?), counting to 100, and a list of about 25 sight words. This is DS's K. I don't recall expectations for DD's K anymore.
