Twelve hardwood solids: 2 cylinders, sphere, hemisphere, cone, pyramid, 6 prisms (including a cube). They range in size from 2" to 3" (5 to 7.5 cm).
WARNING: CHOKING HAZARD! Small parts. Not for children under 3 years.
In addition to using these with the program, these are a big hit with my preschoolers, who love to compete to name and collect the shapes as I pull them out of the bag.
