## Customer Reviews

### ⭐⭐⭐⭐⭐ Bought after watching Shape Island
*by D***H on February 17, 2024*

The trilogy is hilarious and each book is always a fun read. Highly recommend each shape book.I came across the shapes after a recommendation for a Christmas episode on Apple TV, then I found the books here. Better yet! I already had “This is Not My Hat” and “The Rock From the Sky” and I couldn’t believe I had stumbled upon more of Jon’s works.I hope to have more of his stories to read to my kids and maybe even to their kids.

### ⭐⭐⭐⭐⭐ My Class Loved It!
*by A***R on March 24, 2017*

As a first grade classroom teacher, I am always looking for great read alouds to share with my class. This is one! I initially bought Triangle because I loved previous work by both Mac Barnett and Jon Klassen. I also purchased it because we are about to begin a geometry unit and this would be a wonderful way for integration.I was more than pleased with this book! My students (6-7 y.o.) were mesmerized and engaged throughout the read aloud. They were making predictions about what would happen next and debating what they thought truly happened in the end.My first graders loved it so much, that I got it for my 3 and 4 year old nieces. They enjoyed the illustrations and thought the ending was funny. Their dad was overjoyed to have something decent to read before bedtime.This duo has a great chemistry. The simplicity of both Barnett's words and Klassen's illustrations work together create such a powerful narrative; one alone is not as strong as they are together. The characters, with only eyes, have so much expression that my niece picked up on.Do not let the simple words and pictures deter you. The story packs a punch. This is a choice piece of literature.

### ⭐⭐⭐⭐⭐ (Kindergarten Teachers Also) Please Purchase This Book!
*by A***S on May 1, 2017*

I love this book. As a fieldwork student studying to be an elementary school teacher, I used this book to teach an observed lesson on shapes to Kindergarteners. Luckily, I got to focus on triangles and after reading the reviews on Amazon I had to buy this book. Conveniently my students just learned about squares so I could review prior knowledge.Furthermore, I used this book to the fulfill the following CCSS standard on geometry (K.G.B.1 - teaching about squares and triangles) and also on the concepts of tall, medium, and small.Also, when I conducted a read aloud to my Kindergarteners, they loved the book so much. One student even commented on it being the best book ever. Initially, I was worried about reading a book about a triangle being a trickster, but my master teacher had no problem with it. Plus, it didn't really influence my students at all. At least it kept them engaged and tied to the learning goals they needed to achieve.I highly suggest that Kindergarten teachers purchase this book. It fulfills some Common Core standards and is an engaging book with unique illustrations.
