Children can lay out number tags on the Number Tag Mat, then pull it along the side of the chain mat as they count and put out the tags. A must for the Montessori classroom! This superior quality mat is made in the USA out of a soft, 100% poly-fleece; it is durable and rolls up neatly for storage. Machine wash and dry. 20" x 9½". Save when you purchase the Set of 3 Bead Chain Mats (X706). Please note: Before ordering, be sure to measure your Bead Chains because sets vary in length.
