The Sesame Street Numbers Set is a 1973 Sesame Street Colorforms playset. The vinyl Colorforms pieces are in the shapes of numbers and corresponding shapes, which could be matched on the playboard's cartoons depicting Ernie and Bert counting everyday objects. Ernie and Bert sail two toy sailboats, count three sheep before bed, watch four birds fly out of a nest, search in a drawer for eight pencils, and walk through the snow near nine pine trees.
