Kids will get their early math skills in shape with this bestselling picture book--now available in Scholastic Bookshelf! Bored and dissatisfied with his life, a triangle visits a local shapeshifter to add another angle to his shape. Poof! He becomes a quadrilateral. But then he gets greedy and keeps adding angles until he's completely transformed. Kids will enjoy this boldly colorful introduction to shapes and basic math concepts.
Greedy Triangle is written by Marilyn Burns and illustrated by Gordon Silveria and is part of the Sholastic book range.
The triangle is bored with his shape and asks a shapeshifter to add another angle to his shape....over and over again. He becomes many different shapes until at last he he misses his friends and learns that it's not so bad being a triangle!
This book is great for early learners of maths - Early Years, even KS1, introducing the correct names for geometric shapes. It challenges children's misconceptions about the position of shapes 'by showing children shapes in many different forms and positions and places them in contexts that make them accessible to children. The illustrations give children a chance to think more flexibly about shapes and how they are used.
There is great potential for extending children's learning - particularly in Early Years with the suggestions in the book such as role play and investigation of the classroom for shapes. It is a good introduction to a creative art activity where the children could tell their own story using various shapes of different sizes.
I have given this book a high rating because of its versatility and its potential to act as a PHSE model to remind children that being greedy is not the way to have fun or keep your friends - love yourself as you are!
My niece, who is eight, enjoyed this book. It's a fun introduction to geometry cleverly and skillfully disguised as a story about a triangle who is dissatisfied with his same-o same-o life. My niece was absorbed in the book, and she spent time counting the sides and angles on the shape as it changed from a traingle, to a quadrilateral, to a pentagon, etc., etc. She also got a nice little lesson about liking yourself the way you are.
The only downside was that the story got a bit repetitive, which I noticed more when I read it aloud to the kids. Other than that, though, The Greedy Triangle is a well done math-related read.
"But his favourite was to slide into place when people put their hands on their hips. That way he got to hear all the gossip before anyone else and got to tell his friends."
This was a fun and creative little book introducing young children to the regular polygons. The role of the triangle and the subsequent shapes which it became make the abstract concepts of geometric shapes more relevant to young children. I also really enjoyed the subversion of the "shapeshifter" and his colourful scientific methods for adding sides and angles to the triangle. It was an interesting concept and very well pitched at pre-school are children. I couldn't give this book a higher rating because it was very US-centric in the examples given which will make it difficult for non-US young children to relate to. Also, I wasn't sure what sort of message was being sent out by the triangle's friends ditching him when he became strangely unbalanced by too many sides and angles. It would have been more reassuring to children to have the triangle's friends stick by him through his polygon identity crisis.
This book is a two for one special! It opens the discussion of the importance of being yourself and staying true to yourself. It demonstrates what can potentially happen to your friends when you are not true to yourself. I also absolutely adore this book as well, when I’m teaching 2D shapes! There is tons of information in the back matter if the book as well!
This book is interesting. The triangle wants to be better and have MORE sides. A lot of people are like that. This book kind of tells us that more and more things for ourselves, won't really make us happy.
2. Summary: The little triangle loved to interact with others and to always know the town gossip, until one day he decided that he no longer wanted to be a triangle. After several trips to the shapeshifter, and after taking the form of many different shapes, the little triangle learned that he loved who he was after all.
3. Critique: a. One of the greatest strengths of this story is the use of descriptive illustrations to support the text.
b. The title character begins to become bored after living the life of a triangle for all of his days. He decides that a trip to the local shapeshifter will solve all of his problems. The illustrator, Gordon Silveria, provides the reader with realistic images of the little triangle, and all of his other shape friends, in everyday life experiences. The reader is able to visualize items from their average day, which incorporate all of these different shapes, thanks to Silveria’s work.
c. On pages seven and eight, the little triangle, who is now a quadrilateral, takes the shape of a television set, a picture frame, and a computer screen. All of these items provide the reader with realistic examples of where they can find quadrilaterals in their own lives. As a pentagon, the little triangle now takes the shape of a baseball diamond, a portion of a soccer ball, and even the Pentagon in Washington, D.C. (p. 13-14). The examples continue throughout the entire story, not only providing the reader with descriptive details through text, but also through images in the illustrations.
4. Curriculum Connection: This story has an obvious connection to mathematics and geometry for children of many ages. Teachers can use this story to discuss simplistic shapes, such as the square, triangle, and circle, with primary grade students. The teachers can then extend children’s learning by discussing shapes beyond those already mentioned, as well as creating exciting and fun activities for their students. One great activity that teachers could utilize in their classroom is to have students create a triangle, just the like the king and queen in the story, by having students place their hands on their hips. With a partner, they could then trace the triangle that this action creates. Teachers could also take their students on a walk through the school to try and find some of these shapes in real life, just like in the story.
As a triangle, he was very busy doing all the different things that triangles do. All the triangle wanted was to be something special. One day, the triangle went to the shapeshifter, and the shapeshifter turned him into a quadrilateral. He was now happy being a quadrilateral, but he still wanted something more. So, he went back to the shapeshifter and was then turned into a pentagon. Now that he was a pentagon, he became very busy and had no time for his friends. After being turned into a many-sided polygon he decided he wanted to go back to being a triangle, and so he did.
This book can be used in the classroom for many things. One way is that you could use the book to teach about the different polygons. Also, you could talk about all the different shapes we see throughout the day. And you could also use the book to talk about how being yourself is how a person can truly be special and interesting.
Fun Math oriented book where one day a triangle becomes unhappy with his shape. He's bored. He sees a shapeshifter who turns him into a quadrilateral. After awhile, he becomes bored with this new shape and wants another change.Unsurprisngly, at the end, he likes being a triangle best. Message to this story: the grass is not always greener.
Throughout the story, real world items in the various shapes are pointed out and students will like finding the shapes in the illustrations. I like that Math vocabulary such as quadrilateral is used. There is a long note in the back "For Parents, Teachers, and Other Adults" that explains the Math and extends the learning. Fun way to incorporate Math with younger students.
This introduces polygons and their names from triangle through decagon, and it highlights where shapes (triangle through hexagon, mainly) are seen in everyday life.
It shows shapes in lots of orientations, which was nice. *The triangles are most isosceles. *The quadrilaterals for the main character are all rectangles and mostly squares, though there is a rhombus character, as well. *The pentagons are mostly regular or have two adjacent right angles. *The hexagons and higher are regular.
This book is an excellent way to introduce shapes to young children in a fun and humourous way. There are tons of extension activities that can take root from this book. Children can easily engage with the story and track the shapes within. It also teaches some important morals like being happy with what you have and also to be careful what you wish for. Overall, a great read even just for enjoyment.
The greedy triangle just wants to try new things, but that means visiting the shape shifter to see how life can change.
A great message about enjoying who you are and what you do along with bringing situational awareness to where shapes hide. (Triangle’s favorite place is when dancers put their hands on their hips so he can hear the latest news!) Plus the introductions of geometry terms.
I haven't read this yet, but I can't figure out how to add a note to it without rating it first. I feel it is important to note that GR advertised this book to me based on my currently reading Illness as Metaphor and AIDS and Its Metaphors. I look forward to discovering what a "math" book "for kids" featuring intelligent polygons has in common with Sontag's works.
This book introduce kids to different shapes. The triangle wanted to be other shapes because he wanted to have more fun. Since the triangle change into other shapes, the book also introduce sides of the shapes.
Delivering the message that it is always best to be yourself, The Greedy Triangle also introduces children to various polygons on its journey to discover other shape possibilities.
Gladly, in the end, he realizes staying a triangle is just right!
Fun story that takes kids through a journey of different shapes as a shape takes on an additional side. The end of the book includes some helpful concept teaching information for parents, teachers, and other adults reading with kids!
This is a living math book. We love it. Great geometry intro. Discusses shapes from triangle to decagon and beyond, in what my three year old nephew calls a "silly book." He requests it frequently before his nap.
"The Greedy Triangle" follows the story of a triangle who grows tired of being, well, a triangle. He goes to a "shape shifter" to be turned into various other shapes, including a pentagon and hexagon. When visiting the "shape shifter," the triangle repeatedly says, "I think if I had just one more side and one more angle, my life would be more interesting." Sadly, after all of his changes, the triangle loses his friends, growing sad. At the end of the story, he returns to the "shape shifter" to be turned back into a triangle again. He enjoys sharing his stories with his friends and they are "glad the triangle was back in shape again."
Not the most convenient story, however, "The Greedy Triangle" teaches children that, even though they might not like the person that they are, there is nothing wrong with being their unique selves. The triangle learns this the hard way, forgetting about his friends the more "fun" he has being other shapes. The good thing about the book is that it does teaches about various shapes and has a good moral, but it would not be the best text to incorporate into a lesson. "The Greedy Triangle" might be better used during a read aloud circle to reinforce the terminology an educator could be teaching in a math course. Otherwise, it is an easy read that children could read on their own and its colorful illustrations help to keep a reader's attention as they watch a greedy triangle realize that being a triangle is all he needs to be.

Summary: One day, a triangle decides he is unhappy with his life and goes to see a shapeshifter. He asks the shapeshifter for another side, but soon becomes dissatisfied with life as a quadrilateral as well. After many more trips to the shapeshifter to add angles and change his shape, the triangle realizes that he likes being a triangle after all.
Evaluation: This is an all around great book. It does a great job of not only talking about shapes, but providing readers with real life examples of shapes (ex. computer screen, window, and picture frame for quadrilateral). It is also very engaging and has a great message as well.
Teaching Idea: This book would not only be great to use for teaching shapes, but also for teaching students about being themselves and what happens when you’re greedy. I would have students talk about the triangle’s character development throughout the story in order to reinforce the importance of loving who you are and acceptance. When teaching math, I would have the class draw each shape on the board and give examples based on what we read in the book. They will have to tell me how many sides and angles each shape has. I also think it would be fun for students to write about what shape they would like to be and why using key vocabulary such as: side, angle, and shape.
I absolutely love this book. The story starts off with a triangle who begins to grow bored with being a triangle. It goes to the shapeshifter to change its shape to start over. It then becomes a quadrilateral and begins to grow bored of that. Over and over again, the shape grows tired of who it is and changes its shape one side and angle at a time. After a while, the shape loses its shape and wants to return to being a triangle. After it returns to being a triangle, it realizes that that is where it was meant to be. I think this story is really good for an introduction to shapes. The pictures on the pages represent the shape very well and are colored very vividly to keep the attention. I can then point out to the students different objects in the classroom that match, and they can pick up on it easily. Not only does it teach the lesson about shapes, but it also teaches kids about being happy with what they have and not changing a thing about who they are. Overall, I think this is a good book for my students. I will be able to teach my students easily with this book. It is also a book I could build upon with hands on activities for my students. I would use this book in first grade. I think it would hold their attention very well and keep them entertained while teaching them a lesson.
I liked this book because it is a great social-emotional tool as well as math-oriented. I will definitely be able to use this book to talk about different shapes, including the academic language of sides and angles. This book is appropriate in the classroom levels of kindergarten and first. It helps identify and describe basic two-dimensional shapes in their similarities and differences. I would recommend it to kindergarten teachers, and to use at the beginning and during review sessions of shapes in first grade. I would expand the story to a writing prompt: "What makes me...me!". I would want the students to focus on the social-emotional aspect of what makes them different and special from other people. I would also want them to focus on what they perceive to be their best qualities. These conversations can start in mathematics as shapes, but continue into social studies on how each shape has a special job as we all do in society. I would use this book as a hook to the introduction of shapes and gain more vocabulary about shapes. I would want this hook to be followed up by categorizing the different shapes we can label with the number of sides and angles.
The Greedy Triangle is about a triangle who is bored with his shape and goes to a shapeshifter to add another angle to his body. With another angle, he experiences his new life as a quadrilateral.... until he is bored again. He goes back to the shapeshifter and adds another angle. He keeps on doing this over and over again, experiencing what it's like to be a pentagon, hexagon, and so on. It isn't until that he misses his friends, that he heads back to the shapeshifter and learns that it's not so bad being a triangle!
Early learners can learn a lot from this book as it teaches about different shapes and connect them to real-world items. These shapes are actually everywhere! It raises situational awareness and students can try finding these shapes in the illustrations and even in their own environment. In addition to the math themes and terminology, it is also a great way to teach kids about appreciating themselves and being comfortable in their own skin. He realized his value as a triangle and started to recognize his shape everywhere and how exciting it is to be him. it's not good to be greedy. The illustrations are super cute and very whimsical, with a colorful palette to match. The use of real-life settings makes it more meaningful for learning landmarks (social studies).
The Greedy Triangle is a great story to support content areas across the curriculum, particularly Art and Mathematics. In this simple and colorful book, we meet a triangle and learn many interesting facts about its characteristics. The triangle is pleased with the many things he sees in his environment that mimic his characteristics, but after a while, he gets bored. He wants more out of his life and wonders what would happen if he had just one more side. Lucky for him, the Shapeshifter pops in like a fairy godfather to help. With his magic, the triangle changes from three sides to four, and it opens a whole new world of possibilities. So many new things in the world have four sides like the new shape, and he is quite pleased. Until he gets bored. Once more, he wonders what could be better, if he only had one more side. Along comes the Shapeshifter and the shape now has five sides. The story continues with the Greedy Triangle adding one more side, and then another, enjoying his new world. Finally, he has so many sides, he can’t even stand up straight, and he realizes that he really had it all, when he had just three sides.

In the Greedy Triangle, the character- Triangle- is dissatisfied with its shape and decides to change. With the help of the Shapeshifter, the triangle takes on some new identities. When it continues to add different sides or angles, it changes from one shape to another. It first starts as a triangle, then to a quadrilateral, to a pentagon, and other shapes. After so many changes the triangle finds that its original shape is alright and that the character Triangle should be happy with the way it is. In the use of illustrations, the colored-pencil artworks and compositions are seen throughout the book. Through the speckled paint and doodles, the illustrations create a sense of disorder that isn't chaotic.
I'm not really a fan of mathematics but I like the simple concepts seen in the book. The simple change of the shape has the child understand his or her shapes when it's a simple triangle. The title is also another thing that is seen as a misconception since the triangle character is more adventurous than "greedy."
I would use this book for second grade or third grade.
This book had lots of color, and great examples of the shapes in the real world. This book focuses on a greedy little triangle who grows tired of being himself, so he looks to change. This cycle continues throughout the book where he keeps changing shapes, and learning about what he could be.
This book is a great way to introduce kids to shapes and polygons. Kids get to see different examples of the shapes in the world (EX: Pentagon on soccer balls, home plate on a baseball field, hexagon on beehives, floor tiles.) This book is also a great way to get kids aware of where shapes are in the world around them, and the purposes of each shape (triangles help hold bridges, etc)
The lesson/message in this book is also great for kids as it teaches them they are perfect just the way they are, and they have a purpose.
The greedy triangle is a fun and engaging children's book that also teaches about different types of shapes. My children loved reading this book, and tried to name each of the shapes that the triangle turned into. The greedy triangle is not satisfied with his three corners and three angles, so he transforms into a quadrilateral with four corners and four angles. After a while he becomes bored again with this shape, and he continues to transform adding one more corner and angle each time. Eventually he has so many sides that he doesn't know how to stand or walk and he longs to be a triangle again. Finally, he returns to being a triangle and has a new appreciation for all the things he can do with his three corners and angles. This book is a great way to introduce shapes for PreK-2nd grade students. It names shapes from a triangle, adding vertices and angles, all the way up through a decagon. It is a cute story that young readers will enjoy.
The Greedy Triangle by Marilyn Burns is a picture book that introduces young readers to the fascinating world of shapes and angles. This would be a great book to use in an elementary level math classroom to introduce students to geometry terminology. The story follows a triangle that becomes unhappy with its limited number of sides and angles. Seeking excitement and change, the triangle transforms into various polygons, each with more sides. He becomes many different shapes until he realizes that he misses his friends and learns that it's not so bad being a triangle! Math concepts are mentioned throughout the story, making it accessible and entertaining for young readers. The book introduces key geometric concepts such as polygons, angles, and sides in an engaging manner. The Greedy Triangle is a valuable resource for teaching geometry to young children. It not only educates but also sparks curiosity and encourages critical thinking.Ìý
This story has to be one of my favorites! It is an engaging story that personifies a triangle who's not content with being a triangle and wants to explore having more sides and angles. As the triangle transforms into various shapes, from a quadrilateral to a pentagon and beyond, students are introduced to countless different geometric figures. In a first-grade classroom, this book is a fantastic way to introduce or reinforce geometry concepts. After reading this story, teachers could have students create their own shapes with craft sticks or draw them, identifying the number of sides and angles. This cute story is also a great springboard for discussing satisfaction with who we are and the idea that sometimes, wanting to be something else can lead to unexpected challenges. Engaging students in a discussion about the shapes they see in their environment can further solidify the connection between the book and the real world. I loved this book and will be using it in my future teaching!
