Shapes at Play (Board Book)

"Shapes like to play. They like hiding inside other shapes. They might appear different, or completely disappear, but when you divide them, subtract them, enlarge them, turn them, slide them, or flip them, you will see what they are and how they hide. In this simple book, you can discover basic concepts of transformational geometry, scale, proportion, axis, symmetry, and reflection. Can you find all of the shapes?"--
