Kindergarten was my favorite year in school. We could color, have stories read to us, sing songs, make art projects, jump rope, play games, and have milk and cookies.
I even remember one day they took us outside to plant tulip bulbs in the ground (the janitor had dug the holes and we each put in a bulb), in front of the school. Another time, they took us across the street to a little brook, and we watched the water flow downstream, while the teacher told us about fish and plants in the area. Both of those experiences were big fun for little kids.
Sure, this was a long time ago, but kindergarten should still be learning at a more leisurely pace. I think the key element of kindergarten is learning social skills with the other children.
