A unique, hands-on way to teach students about time. Just roll one set of the time dice for the start time, roll the second set of the dice for the end time and then find the elapsed time by using the clock on the mat. Students can show the time by lying on the mat and using their arms as the clocks hands or they can use the plastic clock hands to show the time rolled. Hours, half hours, and quarter hours are reinforced. Time number line on the bottom helps students with elapsed time problems. Mat features grommets for hanging. Vinyl floor mat measures 4-1/2 ft. x 4-1/2 ft. Includes mat, guide, and four 5 in. inflatable yellow time dice. Two with red hours printed on them and two with blue minutes printed on them.
