Save your water bottle caps! Those little guys can be used to make fun center activities! You can write numbers on the top of each cap and have the kids put them in order--I call it the "number order caterpillar". So far my number caps go all the way to 100, but you could try different variations: counting by 5s, 10s, etc. The newest idea I have found for bottle caps is to put student names on them! I love the way they turned out, and they were quick and easy to make--started and finished them during Emma's naptime! You could use these for beginning of the year games, the kids can practice putting the words in ABC order, make 2 of each child's name to create a matching game, or put them in a sack and choose a name for times when you need to pick a helper.
