COPY ISBN Gr 1-4–Shapes that repeat and fit without gaps or overlaps are a seemingly simple jigsaw puzzle problem that hide an even bigger math problem. Not all shapes tessellate, fitting together by repetition, and the puzzle of having a pentagon tessellate has been a conundrum since ancient times. The story approaches the explanation of this complex math problem through a biography of housewife Marjorie Rice and her fascination with shapes.
