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.

Granddaddy Parallelogram and his grandchildren, Rect the Rectangle and Rhombella the Rhombus, live in the land of quadrilaterals. It is an exciting place to be, but Rect and Rhombella have difficulty accepting each others differences. As a result, Rect and Rhombella dispute continuously. Their disagreements cease with self-discovery and a secret from their astute grandfather, Granddaddy Parallelogram. With vibrant color illustrations and accompanying stories children can relate to, the Granddaddy Parallelogram series is a useful tool to teach children advance geometric concepts initially. Children will enjoy entering the land of quadrilaterals and the engaging activities offered to parents and teachers to enhance their childrens knowledge. Experience gratification in math and adventures with the entire Granddaddy Parallelogram series.
