With K’s Kids Shape Sorting Friends, baby can learn shapes one step at a time. First the idea of shapes comes from the soft textured plastic toy teether tubes topped with a friendly K’s Kids pal. Shapes include: round, square and triangle. Next step, baby starts to physically match the teether tubes into the corresponding blocks. There are also more shapes to learn from everyday items: football, butterfly, heart, and a stop sign. You can play “match the shape” with the soft blocks. There is a lot of fun plus learning going on with these soft blocks. Blocks are machine washable
