These mats work best when printed and laminated. These are meant for kids to practice number/word recognition, counting, letter recognition, shape and color recognition while doing a fun activity with play-doh! Kids also practice motor skills during this activity. The object of the activity is to replicate the visuals on the mats using play-doh. The colors used in these worksheets were selected to match a 10-pack of play-doh. (I purchased it at Amazon).
