In which state would you find the Colorado River? Sorry, you're out of time! If you set the table with your educational placemats, you'd know the answer. Each laminated 12" x 17-3/8" placemat is full color on the front, and black & white on the back. Write on the back with markers, then wipe off and start again. You can choose the U.S. Map, Stars & Constellations, or the Periodic Table of Elements - but our favorite is the one that shows the stars, includes helpful information about the night sky, and lets you draw your own constellations on the back!
