26 clip it or pin it centers, one for each letter. Each letter has 12 clip it cards (4 to a page). These centers are meant to be laminated and used year after year. I use a book ring and punch a hole in each card so I can put the ones for that letter on each ring. This makes it so easy to switch it out throughout the week. There is a total of 26 centers. There is also a black and white option for a printer friendly option. Students will place a clothespin on the image that has the beginning sound of that letter.
