This is a great book to use as a math lesson with a connection to literature. So many children hate math until they see it presented in a different way and can make a connection.

The greedy triangle thinks transforming into other shapes will improve his life, but he realizes that squares, rectangles, and octagons don't always have more fun. Math teachers can use this book to introduce various shapes and geometrical terms such as angles and edges.

This book is a good example of a fantasy book. It is a believable story that children would be able to relate to even though the main character is a triangle. The triangle has human characteristics. The main character is round and dynamic. We learn a lot about this triangle and we see the triangle go through a dramatic change. The triangle is unhappy with its shape so it constantly changes shape, but in the end realizes how good it was to just be itself. I would use this book for an intermediate classroom. The main type of media used is pencil.

This is a great book that incorporates different types of shapes. It gives the meaning and a lot of clear examples of n-gon shapes and basic ones. A great activity to do after reading, would be to find shapes in the classroom. For example, ask the the students what in the room is like an octagon, etc. Students could also create a painting based on the shapes they have learned. This incorporates colors and shapes.

A triangle is disatisfied with himself and adds another side becoming a square. The square sees everything he can be apart of such as a home, a square tile, and much more, but he wants to be bigger and better and becomes a pentagon. The book goes on telling what shapes are used in different things. This is a great math introduction to shapes.

This book is a great easy math book for young children. It teaches geometric shapes. And it tells a fun story about being yourself.

A greedy triangle is not happy no matter what shape he becomes. In the end, he realizes it's better just to be himself. This story teaches a lesson in acceptance as well as the concepts of shapes and geometry.

This is a great book to read before a math lesson or reviewing for a math test. It is about a triangle who always wants one more side to make his life better. He goes to the shapeshifter and he changes him into a quadrilateral and he continues this until he has many many sides.

The Greedy Triangle is all about a triangle who is not happy with it's three sides and angles. The triangle goes to the shape shifter to give him just one more side and one more angle so he became a quadrilateral. Over time the quadrilateral became dissatisfied and wanted another edge and another angle to become a hexagon. This goes on and on until the shape doesn't even know how many sides and angles it has. It decides to go back to being a triangle and is happy with its final decision.

Probably one of my favorite books that I have come across! I love the vocabulary and how many teaching opportunities there are. I also love the meaning behind this book and how we need to enjoy who we are!

What fun introduction geometry is, as the book explains a greedy triangle that¿s ready to try new shapes and sizes? This particular triangle is trying to find itself by exploring different shapes like a square, polygon, octagon and even a circle, but only to return to its original triangular shape. Not only is this book an introduction to geometry but also a story for children to feel comfortable in their own skin.

A triangle is never quite satisfied in life, so he keeps adding sides and turning into a different shape, forgetting who he is and leaving his friends behind. A cute way to review shapes with students. I like how real-world examples are given each time the triangle becomes a new shape.
taramankin on LibraryThing 22 days ago
This would be a great book to share with children learning about shapes. It's about a triangle who is tired of being a triangle so he goes to the shapeshifter to be changed. He becomes many different shapes but none satisfied him. He went back to the shapeshifter to become his old shape again, the triangle and was very satisfied and happy again. This story shows a lesson that the grass is not always greener on the other side.

This is a good book about vocabulary. This books is more for a math class but it has wonderful geometric vocabulary. I would use this for a read aloud.

A triangle wants to branch out and try some new angles. This is a story of accepting who you are and what you are meant to be. It also incorporates a little shape lesson for students.

Great book for geometry!
Leshauck on LibraryThing 5 months ago
This book is good for teaching about shapes and colors. I would use it for all grades. The book does not have a very strong story line.

The 'Greedy Triangle' wants to be this shape and then that, but in the meantime, your child is learning. New to kids and a refresher for adults.

The greedy triangle wants to change into different shapes. You should get this book!

The Greedy Triangle is a most unusual book in that it will appeal to three age groups, 4-5 year olds, those learning polygons for the first time, and for adults who never felt that comfortable with geometry. The book opens up the reader's mind to seeing geometric shapes all around, while providing a simple basis to remember the differences among polygons (they each differ in having one angle and side more or less than the most similar polygon). 'Once there was a triangle that was -- as most triangles are -- always busy.' The book points out some of the many frequent places where triangles can be found such as 'holding up roofs, supporting bridges, making music, catching the wind for sailboats, being slices of pie . . . and more.' 'The triangle's favorite thing, however, was to slip into place when people put their hands on their hips.' This last refers to the space between the arm and the body. The triangle likes this shape because 'that way I always hear the latest news . . . which I can tell my friends.' And his friends like that. But the triangle finds this boring at some point, and seeks the help of a shapeshifter to become a quadrilateral. Ennui recurs and the former triangle moves through a transition successively into a pentagon, hexagon, heptagon, octagon, nonagon, and decagon. For the first few shapes, the book outlines places you find these shapes in nature and human-made objects. A connection is also made as to whether those shapes provide juicy stories to tell friends. There is adult humor, such as noting about not being able to tell secrets learned at the Pentagon. Eventually, this all becomes self-limiting. 'Its sides were so smooth it had trouble keeping its balance.' 'Its friends couldn't tell which side it was on and began to avoid the shape.' The shape fell down a hill. 'It felt tired and dizzy, lonely and sad.' 'I want to be a triangle again.' The shapeshifter said, 'I'm not surprised.' The book has an excellent guide in the end for parents, teachers, and other adults. This includes great exercises to extend this knowledge for your child. This section also explains the terms more precisely, and defines an undecagon (11 sides) and dodecagon (12 sides). The illustrations are in bright, electric versions of pastel colors that effectively emphasize simple shapes in their most abstract forms. I was impressed by the sections that use examples of the shapes. Some of them I had never thought about before. This is a great way to stimulate subconscious learning. I also enjoyed the many 'punny' expressions, obviously designed to amuse the adult readers. If you don't like puns, you will probably think the book is a little corny. The book's only weakness is that the story is too predictable. That limits its appropriateness for older children. They need more complications in their stories. Since the book is aimed 4-8 year olds, it doesn't hurt a bit for the 4-5 year olds but will lose you some 6-8 year olds. This predictability is fine for new geometry students, because getting to read something more interesting than a textbook is a thrill at that point. For permanently polygon-puzzled adults, the book will seem very down-to-earth and accessible. I also suggest that you ask your child to extend the contents of this book to identify other shapes that are not polygons (such as circles) and specific types of polygons (such as squares, parallelograms, and trapezoids). You can use the exercises in the end of the book towards these shapes, as well. Reshape your perceptions of polygons!
