This classic HABA favorite allows children to learn to hammer using real ½" nails and a wooden mallet. Children place a nail in the pre-drilled hole in a tile, and then hammer to affix it to the cork board. Develops and encourages fine motor skills as they work. Tiles can be removed from the cork board, then re positioned to create an infinite variety of patterns and pictures. Comes with suggestions for designs, including a flower in a pot, a bird, a barn, a watering can, and a windmill. Of course, because of the open-ended nature of this activity, children will be able to create their own original patterns and pictures with the geometric tiles. Includes a design sheet, wooden mallet, 100 geometric tiles, 125 1/2" nails, and cork board measuring 11.5" x 8.75".
