Clip cards make great centers. They are easy to make, just print, cut, and laminate. I punch a hole in each card and then clip them together with a ring. They can be interchanged for each theme you do. But I especially like clip cards because the kids can do them independently and they are easy for me to assess with just a quick glance. Also, because we use them with regular clothes pins, they are great fine motor practice!Check them out at my TPT store!
