Perfect Square starts with a red square on Monday and on each day of the week he explores all the things you can make from different color squares. From a red square, he shapes a fountain that babbles, giggles and claps. He shapes an orange square into flowers and a green square into a park. Young ones can guess (or remember) the cut up shapes of each square and what they turn into. A surprise at the end reviews all the shapes. The colors are bright and vivid, the shapes are clever and simple. A delight to explore while learning colors, shapes, and days of the week.
