I open at 7:30 but usually have all my children arriving at 8am so breakfast is served shortly after 8
9 - 11 outside field trip to library, parks, or inside rainy day play in my toyroom - 1-2 days per week are learning/crafting days
11 preparing lunch - the children freeplay
11:30 lunch
12:00 circle time
12:30 nap/quiet time until 2:30-3ish
3 afternoon snack
3:30-4:45 pickup times vary so the children freeplay

I do the same songs for all age groups but the older children like to play extra games like What Time is it Mr. Wolf? or Red light Green light or Musical Mats (instead of chairs), etc.

I find that as the age group changes my times change slightly. Experiment and do what works best for your group.
