Print and laminate this sheet on card stock for as many mats as you wish to have for students (I usually do four kids at a center). Next, you will need to laminate the same number of mats but this time cut them out with a circle cutter/puncher from Hobby Lobby or Walmart! Glue all of these to water bottle caps and they fit perfectly!! You can extend this activity by deleting some of the numbers and having the kids fill in the missing numbers...you'll just need to modify it in word where you save it and print new mats!! Great for number recognition and you could even apply to addition later on!
