My son is finishing up his year of kindergarten this week!!

Aside from academic things, the most important thing was independence. For example:
- bathroom (need to do everything by himself - pants down, potty, wipe, pants up, zips/snaps, wash hands, dry hands)
- clothing (need to put shoes on/off, tie or velcro shoes, put jacket on/off along with gloves/hats)
- lunch (open/close lunchbox, juice boxes, thermos, tupperware)
- identity (know name, address, phone number, parents name, birthday)
- backpack (knowing what's inside, what needs to be brought into classroom, what needs to come home, where to store gloves)
The other thing I would recommend is practice writing and drawing. Stick a pencil, crayon, chalk in their hands constantly!!!
