The weather is getting very nice here and that makes me move everyone outside. We like to take many of our indoor activities to the play yard when it's nice, but sometimes it's nice to have a little specialized equipment.
This first picture is a plexiglass wall that divides a small deck that stretches between the toddler yard and the 3s/4s yard (we often leave the gate open between them, so this distinction is really in the minds of the teachers only). It can be painted on from either side. It's starting to get a little weathered and cloudy, but you can still see through it. The nice thing is that it's two activities in one. The kids can paint first, and then clean it off. We've used brushed with water, sponges, the hose, and wet towels to wash it off, but I'm sure you could think of some other ideas.
Another nice thing to have is a plexiglass easel. The nice thing about it is that you can move it around, unlike the wall. We also bring our regular easels out, but we have just one of these see-through ones and it's always a hit. Maybe the fun is in painting directly on the easel with no paper or that you can see what the other person is doing on the side at the same time. I don't know, but it's cool. Sometimes I think the adults are more taken with it than the kids are!
