    The Greedy Triangle

    An offbeat introduction to geometry. When a triangle tires of having only three sides, he asks the shapeshifter to change him first into a quadrilateral, then a pentagon, a hexagon, and so forth until he realizes he is happiest as a triangle: he can hold up a roof, be a slice of a pie and, best of all, slip into place when people put their hands on their hips.

    The text is clever and shows more than the usual places to find shapes. The acrylic and colored-pencil illustrations are colorful, abstract, and filled with smiling shapes. A two-page spread of suggestions for adults to reinforce the math lessons featured is included at the end of the book.


    Sir Cumference and the First Round Table: A Math Adventure

    When King Arthur and his knights get together, the table they have is so long that everyone has to shout to be heard. A rectangular table is too long and a triangular table is too pointy, but somehow they must sit down and discuss the shape of the future. Join a knight called Sir Cumference, his wife, Lady Di of Ameter, and their son Radius as they use different strategies to solve this quandary.

    The Shape of Me

    Subtitled "Dr. Seuss's Surprising Word Book," The Shape of Me and Other Stuff certainly lives up to its billing. In this delightful book, kids are encouraged to ponder shapes they may never have considered before: "Just think about the shape of beans and flowers and mice and big machines!" Soaring well beyond the mundane arena of circles, triangles, and squares, here we are challenged to consider "the shape of camels the shape of bees and the wonderful shapes of back door keys!" Kids will love the silly rhymes and funny pictures, and parents will appreciate this original take on the largely untapped world of shapes.

    The Shape of Things

    An introduction to six basic shapes illustrated with bright cut-paper collages. The book begins with "A square is just a square... Until you add a roof, Two windows and a door, Then it's much, much more! On succeeding pages, a circle becomes a ferris wheel, a triangle changes to a sailboat, the rectangle is used to form a railroad train. Other more unusual shapes are also pictured: ovals and diamonds become eggs and kites. The final pages are crowded landscapes that contain all of the shapes. Borders of each spread show the featured shape that appears to be stamped with a potato-cut print. An effective concept book with many possibilities for spin-off activities at home and at school.

    First Shape Book

    This delightful early learning book is the perfect way to introduce young children to basic concepts of shape, size, and appearance.
    By becoming familiar with circles, triangles, squares, and rectangles, a child will develop the skills used in writing and early math.
    By finding these shapes in different contexts, a child will develop the skills used in reading and writing.
    By identifying differences in size and between two-dimensional and three-dimensional objects, a child will develop further skills used in math.

    Cubes, Cones, Cylinders, & Spheres

    The photos stand alone in this textless three-dimensional mathematics book. Four small, labeled diagrams on the back of the title page define the shapes. After that, readers are led on a treasure hunt for those shapes through 21 crisp, colorful pictures. A display of teddy bears in clown hats, a basket of baseballs, a breathtaking castle, and sculptured hedges typify the broad-ranging subject matter.

    Math teachers approaching solid geometry will find this to be a useful resource. Children will simply enjoy identifying the plethora of shapes to be found out in the world if one only takes the time to look.
