I received a free ARC from NetGAlley in exchange for an honest review.

I love all the books in this series. They are funny and different. The illustrations help the story.

Mac Barnett is back with another fantastic title. This series is always fun, and great to engage young children wth some first concepts whilst still being an enjoyable read for kids and adults alike.

These books can be a bit difficult at first for kids, but as the story progresses children become more engaged and invested to see what happens to the shapes.

In this book, Triangle gets into a bit of a scary situation when she breaks a rule from Circle. The illustrations leave a bit to be desired, the dark tones and simple shapes can be visually...bleh.. but once children warm up to the story and characters, it works.

This is definitely a book to get for your children. They will ask to read it over and over.

Circle and his friends, Square and Triangle, are playing hide and seek when Triangle breaks the rules. He goes behind the waterfall. Circle goes to find his friend. He gets mad at Triangle but is relieved when he finally finds him.

This book is about shapes but has a good message about following the rules, putting yourself and others in danger if you don’t and putting aside your fears to help a friend.

I loved that the book was about shapes. It repeated the shape’s names throughout to help children learn them through repetition. The underlining themes are important, as well. Teaching children to understand the consequences of their behavior is important. Circle is a good friend because he puts aside his fear to look for Triangle.

The dialogue and illustrations are simple but effective. The colors are neutral which, rather than detract from the story enhance it.


I received an ARC from Candlewick Press through NetGalley in exchange for an honest review. That in no way affects my opinion or rating of this book.

The shapes series by Mac Barnett and Jon Klassen are such a delight. They're some of my favorite storytime reads and Circle will be joining that rotation.

This might actually be my favorite of the Jon Klassen's shapes books, which is saying a lot! I loved the other two books in this series. This book was a little creepy in the best way. It also may help kids who are afraid of the dark if the child does what Circle, Square, and Triangle do when they aren't sure who or what they encountered behind the waterfall.

Thank you NetGalley for the review copy of this book. It's hard to beat Mac Barnett and Jon Klassen. The illustrations are simple and beautiful. The story shows us Circle's bravery and what a good friend he is to the other shapes. I especially love the invitation to image at the end of the book. This is the perfect story for preschool kids.

At long last, the shapes are all together where they should be. We have been waiting for what feels like forever for the third and final instalment of Mac Barnett and Jon Klassen’s shape books, Circle. Much like Triangle and Square before it, Circle is a simple little story about friends.

Circle, Square and Triangle are all playing a game of hide-and-seek. Circle is the counter and warns the others not to go behind the waterfall, it’s dark in there. Typically, the mischievous Triangle does not listen.

Much of this story takes place in the dark behind the waterfall. Jon Klassen’s perfectly descriptive eyes, tell the whole tale of what goes on when Circle heads off in search of Triangle. I don’t want to give anything away so I’ll leave it at that. You will have to read for yourself.

There are so many awesome things about this book and this little trilogy but what I love best is since all of the shapes are together in Circle, you can make predictions about their behaviour based on their depictions in the other two books. Your children will get so much more enjoyment out of the books if you can read them in order starting with Triangle, then Square and finally Circle. According to the Ministry of Education here in Ontario our children need to improve their math scores. Why not make math 10 times more enjoyable by incorporating these excellent books into your lessons on two-dimensional shapes?

Take time to read the information about the author/illustrator at the back. The acknowledgments/author-illustrator information is one of my favourite parts of a book. These pages can be quirky and silly and fun to read.

I just love these books, and I was so excited to see the newest one! Brave circle has to enter a dark cave hidden behind a waterfall to find triangle. Only someone else is there too. Who could it be?

Having read the first and second books in this series, I was looking forward to this one a lot. It did not disappoint.
However, that being said, "Circle" is the least of the three and I would much sooner go for "Square" or "Triangle" given a choice.
Still, any child, or their parent, would have fun reading this one any of these books. They are a great addition to any library.

My kids and I are big fans of Mac Barnett and Jon Klassen's work, and we were excited to read "Circle"! We all enjoyed it immensely. Jon Klassen's illustrations are funny, and Mac Barnett's story was charming.

Circle brings round the entire cast of the Shapes Trilogy for one final game of hide and go seek. Mac Barnett and Jon Klassen expertly craft another amazing picture book full of tricks, honesty, and imagination. I have a feeling that some readers will be frustrated <spoilers> with the ending</spoilers>, but it worked for me!

What is better than a triangle and a square? A circle of course! When Circle, Triangle, and Square decide to play hide-and-seek, circle only has one rule - no hiding behind the waterfall because it is dark. Square was fine with that, but Triangle wasn't afraid. When Circle finished counting and opened her eyes, Square quickly pointed out that Triangle had gone behind the waterfall. Circle was very brave and said she would go find him. When Circle gets behind the waterfall in the dark, does she find Triangle? What happens when Circle sees more that one pair of eyes in the dark? Read this precious story to find out what happens!

I absolutely love Mac Barnett's Shapes Trilogy, and so do my kids! I love the dry sense of humor throughout these books! I know that this is supposed to be the final book of this trilogy, but in my opinion Mac Barnett needs to get rid of the word "trilogy" and continue writing these amazingly funny books! What shape would you want next??

The combination of Mac Barnett and Jon Klassen never disappoints. This the latest of their shapes series and would make a great gift or addition to any children's library. The humor in the book entertains both children and adults. And the illustrations are wonderful.

This is a very simple book, perfect for young children who have trouble staying focused. Without the bright colors and busy pictures, this book does not offer too many distractions. The child instead, focuses on the characters; Circle, Square, and Triangle.

Although two of the shapes are referred to as he or she, they have a gender-neutral appearance. In the end, it hints at not being afraid of what you can't see. I think this a good, quick read for young children.

We are big fans of Mac Barnett. The shape series has been a lot of fun for the kids and are constantly checked out.

My son is 8 months old so I wasn’t yet familiar with the Shapes books, but now I need them all! I adored the themes of fear and imagination in this book. When you don’t know what’s with you in the dark, it may be scary, but just think of the wonderful things it could be and your fear will alleviate! It’s a great lesson on how imagination can dictate emotion. That the characters are shapes helps solidify those words in a child’s mind, and the word choices are very intentional. This book will definitely help a young reader learn!

I have been anxiously awaiting the completion of the Shapes trilogy and the time has finally come! I loved this one. It is just as quirky and thought provoking as the first two. I love how each shape has it's own personality and how they have stayed true to those personalities through-out the three books. As with Triangle and Square this book asks questions of its reader and doesn't provide easy answers. Again as with the first two, it can be read as simply a fun, weird book with cute illustrations or you can use it to spark a conversation and get your kiddos thinking and making guesses. My only qualm with it, and it is a small one, is that I don't think it works as well as a stand-a-lone as the other two. That doesn't bother me too much because I think they are all best read as a trilogy and I would always read them together. If you enjoyed Triangle and Square you should read them again then read Circle. If you haven't read Triangle or Square, you should read them then read Circle.

Advanced copy provided by NetGalley in exchange for an honest review.

Circle is the perfect ending to the shapes trilogy by Mac Barnett and Jon Klassen. At the end of this book, the reader gets to imagine what other shapes their are. Use in a classroom when teaching about shapes.

Circle, Triangle and Square are friends who play hide-n-seek. Circle warns her friends not to hide behind the waterfall, but Triangle disregards her warning.

The graphics are visually appealing, and it was actually the graphics that lured my daughter to the book. She saw me reading the e-arc (thank you NetGalley) and begged to read the book with me. We both loved the simplicity of the graphics, but the story itself was strangely lacking. After reading the story once through, my daughter forced me to re-read the story out loud. She was convinced that she had missed something. We "accepted" the story after the second read through, but we both acknowledged that the story needed a more tangible purpose.
