This year I am teaching just 3's but last year I had a mixed 2/3's class. Most of the 2 year olds were 3 by October, so I ran a 3 year old curriculum in room. Here is my daily schedule (my playground and music/spanish class times are set and cannot be changed):
9am-9:10- Arrival/Welcome Activity (activities on the tables)
9:30-10- Spanish or Music Class (alternate weeks)
1030-1040- Bathroom/Wash Hands/Water
11-1145- I do open centers (assistant supervises) and I call children for small group science/math and art.
11:45-12- Story Time/Music and Movement/Closing Circle
The first few weeks will be an adjustment stage, if they are not in daycare, it will be a new experience for them. Some will cry, some won't. In my experience the crying will lessen a little everyday until they come in smiling around week 2 or 3. You will be able to adapt your schedule and curriculum when you get to know their personalities and abilities.
Let me know if you have other questions!
