Counting, adding, subtracting and learning how to write your numbers is hard. This mat tries to make it a bit more fun. Each mat features a place to practice writing the numbers 1-20 and a space at the bottom to practice counting and writing math expression. This mat pairs well with our Letters Practice Mat too! All of our placemats can be used with chalk, dustless chalk, chalk crayons or bright dry erase crayons. To clean, just wipe off with water, any cleaning spary or use a little dish soap with the water. Each mat measures 12"x17" and has numbers printed on one side and is blank on the other. The mat is Made in China but whenever possible or practical our mats are printed in our Cedar Springs, MI location. This item comes with minimal packaging. Each mat has a full color care label with UPC code for easy scanning.
