A great book to get children thinking about the shapes they see in the world around them. The first few pages ask children to run their finger around the edge of a square, circle, rectangle, hexagon, and triangle. Then there is a page showing three different squares and the next page showing five different triangles that ask children to look at how they are similar and different. The next part of the book is great for talking about going on a shape hunt—there are photographs where children can find rectangles, squares, triangles, circles in the real world—even hexagons in the honeycomb. On page 16, the author introduces the word tessellation to describe shapes that fit together without leaving spaces. While the word is probably new to children, its probably a concept they have experienced when building in the block area or making designs with the pattern blocks. Math extension Go on a shape hunt in your classroom, your school, and outside. Find circles such as clocks, knobs, or stools. Find rectangles in windows, art paper, or photographs. Have children cut out their own shapes and glue them onto paper to make pictures and designs. Home activity Ask children and caregivers to go on a shape hunt at home.
