The Big Green Square (and the little shy frog) (ConceptTheater Book series) (Shape Theater)

The little frog who sticks his head out from behind a SQUARE is surrounded by shapes, a yellow TRIANGLE cheese, a bright gold STAR, a bouncy ROUND ball and more. Each shape is a distinctively, brightly colored object which a child can hear, touch and fully experience -- in an educator-proven strategy of teaching basic concepts. Ages 2-4.
