The kids beg to play with these. They have no idea that they are learning all kinds of things...sorting, categorizing, sequencing, colors, matching, numbers...the learning is endless! We try to only pull these out once or twice a month, that way they think it is a treat, and it is a great activity to do when the weather is bad and they can't go out to recess!
This one has pictures of several items and they divide them into HOT and COLD.
This one lets them put the missing alphabet letters in the right order.
This one is more like a beginner puzzle, they match not only the colors of the hearts, but also the shapes of the edges.
These three are matching...the animal fronts to the animal backs, the patterns on the chicks to the patterns on the baskets, and the pattern on the bees to the matching pattern on the flowers.
And who doesn't love cupcakes? With cherries? Match the numbers of cherries with the number on the cupcake! They count the cherries, then use their number recognition.
To make your own file folders, you will need file folders and an idea. We laminated ours so that they would last longer through repeated use, you will probably want to do that, too.
You can buy books that have file folder ideas in them at book stores or teacher supply stores. You can also download and print from sites like this http://www.filefolderfun.com/SearchPreschool.html, they have free downloads. Also try googling "file folders" for more ideas!
