I am wondering how many of us do some sort of formal educational programming in our daycares?

My program is structured through out the day and we do crafts/activities for special events but that's about it. I didn't find circle time went over that well so I scrapped it. We do about 30 mins of stories before naps though. My kids have very little free time inside as we spend a good chunk of our time outside which I guess is free time as well. My kids are happy but I am wondering if I should be doing more. None of my 3 year olds know how to write their names so I think this would be an important first step. When doing something like this, do you sit with each child 1 on 1 or as a group? I find we don't have a ton of extra time through out the day and do most of our learning naturally.

Thoughts? Am I just being lazy or should I offer more?
