Nine foam tiles lock together into a hopscotch grid 71.5 inches long and 24.5 inches wide, and three foam marker discs come along for tossing. Each numbered tile measures 12.5 by 12.5 inches at 0.4 inches thick, and the number lifts out of the tile so children can reorder the sequence or leave the blanks as a plain floor surface. EVA foam gives a cushioned landing for jumping, and the textured face grips tile, laminate and hardwood so the grid stays put during a game. The whole set weighs 1.3 pounds, light enough for a child to carry from the playroom to the porch and lay out without help. Suitable from ten months, it works as a counting and number recognition activity long after the hopscotch phase ends.
