kindergarten color wheel umbrellas with fingerprint rain. Not sure what kind of colour wheel this is, but I like the concept. I find it helps for future concepts to always have the complementary colour directly across from it's mate.
Simply print out the owls write the child's name then cut them out. They can be put on lockers, backs of the chairs or as a door decoration. There are colored ones or black and white ones. The black and white ones could be a first day activity for the children to color, cut, and write their name on the tag then put it up on the doorway.
