I wanted to share a little idea I got from a friend that is a definite time saver. We all know painting can leave a very messy cleanup. My friend, Stacy, introduced me to paint cup liners. Have you heard of them? They make cleanup so simple and they are cheap! : )
Now for people from my generation you will recognize them right away.
These are the original sandwich bag, long before ziplocks had been thought of.
As you can see, there is no zipper, so it works perfect to line a paint cup.
There you have it and it is a cinch to clean up! Sorry it's blurry.
Another idea I have been using since I first started teaching kindergarten 14 years ago is to use empty coffee cans as trash cans when groups are doing a cut and paste. My old metal cans were all covered. I haven't done anything to the new plastic ones, they would be a little harder to cover. They work great, I usually put 2 on a table if there is going to be a lot of trash and if there isn't much trash, I use one can.
These ideas may not be knew, they were new to me when I started to doing them and they have been very helpful.
