Shape Up!: Fun With Triangles and Other Polygons

Cost high. Content ok.

Interesting and fun way of teaching shapes

Finding books that address math concepts in the upper grades is more challenging. This book is superb because it not only gives critical details on the different types of triangles and quadrilaterals that are polygons, but explains how you can measure the angles within those shapes. Constructing and using a folded piece of paper as a right angle, students are directed through pictures on how to place their right angle on the shapes. Then through comparison knowing if the angles were larger (obtuse) or acute (smaller). Food entices students and the colorful cartoon-like format stimulates students' interest.

I love to use food with my lessons because kids are always hooked in with it. This book guides the students into manipulating food such as cheese and bread to create polygons. It also uses pretzels to create angles. I will definitely be using this book with my 3rd graders.

Great book for learning about shapes.

A great addition to my math books for my students to read during Daily 5 Math. David Adler is a great author!
