A basic introduction to the concept of fractions.

In this introduction to polygons, a triangle convinces a shapeshifter to make him a quadrilateral and later a pentagon, but discovers that where angles and sides are concerned, more isn't always better.

In this wildly amusing, unconventional shape concept book, Trapezoid is here to declare that he's a shape, too. He's NOT a type of dinosaur! Shape up, shapes! Triangle is hosting auditions for all the best shapes to be in his play. Circle, Square, and Star each get a part. But Trapezoid just doesn't "fit in." Is he even a shape? The others think he sounds like a type of dinosaur. Determined to show off his usefulness, Trapezoid tries to act like the other shapes, to no avail. Eventually, though, Trapezoid celebrates his own distinct shape properties in order to become part of the performance.

A hands-on introduction to polygons that takes the fear out of math and puts the fun back in! Draw three dots on a piece of paper. Or maybe-- draw three dots on a slice of cheese. What happens when you connect the dots? With bright, colorful illustrations and a simple, funny text, Shape Up! introduces triangles, quadrangles, and other polygons to young readers, encouraging them to play along, and learn everything there is to know about shapes. Explaining basic geometric concepts and offering definitions for important vocabulary, this introduction to shapes, lines, and angles is to good to miss-- even if the jokes can be a little . . . cheesy. Created by a respected children's nonfiction author and former math teacher, this is a perfect grounding in basic shapes-- and a lot of fun, too.
