The days of chalking Hopscotch squares on the sidewalk are over. The Princess Hopscotch Foam Play Mats ($9.99) from Disney and What Kids Want, provide nine foam mats that interlock, connecting squares 1-9. Squares, numbered 1 through 8, feature a different princess or female character from a Disney fairytale and the ninth square is a castle where all princesses go to live happily ever after. Screen-printed, color images on each square are easy to assemble and help kids ages three and up learn to count. The play mats also come with four space markers and a clear bag for convenient storage.
