I run a preschool and I do about 15 minutes (morning meeting), then 20 minutes (small group), then circle/storytime (20 minutes). So...a total of 55 minutes for the day. Some days is slightly more or less. The rest of our day is free play and outside time and meals, snacks and nap.
I feel that for 3-5 year olds doing around an hour a day or less of ''structured" activities (most of that is actually singing, dancing and open ended art) is more than enough. Free play is where it's at.
