These quality learning tools are 12" x 17.5" and are custom laminated, brightly colored, and very detailed. Children can master a new subject and adults can brush up on old ones... and at such a reasonable price too! The placemats are interactive, with a durable non-glare laminate on the front and many with write-on/wipe-off laminate learning exercises on the back. The exercises are fun and will keep the kids busy for a long period of time.
