Hey momma's, so my son is 4 and will be starting Pre-K this coming school year. What should he know by then? He can count to 20, knows his ABCs, all his colors, animals and sounds, he can identify only a few letters, he is very talkative and can hold an intelligent conversation with you. I just don't know what all he needs to know by then. I've never had to do any of this being as he is my only kid, so I would like to know where he needs to be at to go to Pre-K. Thank you!!!
