The Learning Resources PlayFoam Shape & Learn Alphabet Set allows pre-schoolers to learn and practice lowercase letters. Features 8 colored Playfoam bricks and 13 double-sided letter cards. Children practice letters by putting squishy, squashy PlayFoam on top of the cards and molding it into the desired shape. The numbered instruction points on the letter cards demonstrate how to construct the letter. Child-friendly PlayFoam just stays to itself; it doesn't stick to carpets or fabrics. It's non-drying and ready to use right out of the box for sculpting pleasure. Set includes 8 bricks (white, pink, orange, blue, grey, green, yellow and purple) and 13 activity cards to practice letter formation. Product measures approximately 12.5 cm high.
