Summary:
This story is about a triangle who gets bored with his life and becomes convinced that the answer to his his problems would be to feels that his life is boring because he was doing the same old things like holding up roofs, supporting have just one more side and one more angle. So he went to his local shapeshifter who turned him into a quadrilateral until he became bored of that. Then he turned him into a pentagon but every shape he turned into to became boring after a while so he kept asking for an extra side and angle. Eventually, he had so many sides that he didn't know what to do with himself. His friends began avoiding him because they couldn't tell which side he was on and he became lonely. He went to the shapeshifter one last time and asked to be a triangle again.
Rating:
I recommend this book for teaching geometric shapes to k-2nd graders. It might be a little long for kindergartners with short attention spans but I find it ideal for 1st and 2nd graders. I think it is cute because people in general can relate with the triangle when he gets bored with his life and thinks that the grass is greener on the other side. Kids can also relate because they may feel like their life would be better if they could change something about themselves and it may help them see that they are perfect the way they are. It also gives them exposure to different terminology for shapes. (Ie, quadilateral for square).
Classroom Ideas:
-Shape search- Assign students a particular shape and have them look around the classroom or home (if assigned for homework). Then they can write each thing down or draw what they see.-Make a graph and see which shape they see more of in the classroom.-Make a collage from magazines of the different shapes they learned.
