Charlie Piechart’s second math mystery takes place at school—when a purple, sparkly cone-shaped princess hat goes missing! Margot needs her hat in time for the school play (today!), so Charlie and his dog companion, Watson, are on the case—finding evidence of sparkles and purple paint and keeping on the lookout for geometric clues that might lead to the missing hat.

Fantastic colors, clever characters, and beginning concepts in geometry will go down easy as pie, while activities at the end of the book will reinforce the shapes and the story. Dynamic duo Eric Comstock and Marilyn Sadler bring the right level of energy and entertainment for this engaged picture book audience.

Editorial Reviews

From School Library Journal

K-Gr 2—The second mystery featuring the boy detective with a pie-chart body is built around shape concepts. When Margot's hat disappears, she asks Charlie and his dog assistant Watson to discover its whereabouts. Their school-wide search for a cone-shaped hat sets up opportunities to introduce and compare cylinders, spheres, and other shapes. Most of the geometry information is woven fairly seamlessly into the mystery plot. A ring of purple sparkly paint, for example, is a key clue but also demonstrates that the bottom of a cone is a circle. The backgrounds of several scenes are peppered with a variety of shapes that catch the eye and support the theme; a few of them are even clues. The mystery is not especially compelling, and the geometry content is strictly introductory, but the combination works pretty well. Retro-style illustrations lend a slightly goofy tone, adding just the right touch of humor to the otherwise straightforward narrative. Observant readers will notice visual hints about where the hat might be; even the dog figures it out before Charlie. A final scene reveals that the principal's hat has also been missing, prompting readers to trace backward to find out how it wound up on Watson's head. Two simple projects at the end have instructions for creating a hat and a rocket; both items tie in neatly to the story and to the featured shape of the cone. VERDICT A good choice for libraries in need of more STEM-related materials.—Steven Engelfried, Wilsonville Public Library, OR

Review

Praise for CHARLIE PIECHART AND THE CASE OF THE MISSING PIZZA SLICE: “A lighthearted tone and newcomer Comstock’s playful graphics, which have a weathered, retro quality, make the lesson go down as easy as pie.” — Publishers Weekly

Praise for CHARLIE PIECHART AND THE CASE OF THE MISSING PIZZA SLICE: “Debut illustrator Comstock’s digital artwork is a retro-modern throwback. Kids will have fun following Charlie as he solves the mystery and reinforce their fraction skills along the way.” — Kirkus Reviews

5.0 out of 5 stars We love this book

We love this book! Such a fun and creative way to think about fractions and absolutely full of personality (the illustrations are fabulous and the quirky little details like the tiny bugs in the couch are adorable) Our child is three months old, so doesn't quite get the fractions...or words, but he can't get enough of the pictures. Charlie was actually the first image our little boy really loved to look at. We regularly read the book to him and just watch our boy's eyes scan Charlie's face and smile. When we planned our nursery, we just had to fill it with the things we love, because we obviously hadn't met this little person yet to be born. It's been so much fun to watch our boy's eyes light up to Eric's work just like ours do.

I purchased this book for my granddaughter. She loves it! Ms. Sadler's inventive writing encourages children to learn essential and sometimes difficult math concepts through entertaining writing and interactive activities. Incorporating the activities is especially helpful for my granddaughter because in her math class she is required to not only recognize, but also draw and partition shapes. I highly recommend this book to help children understand shapes and geometry concepts.

2.0 out of 5 stars Charlie is a member of the math club; Margot is a princess with a sparkly hat
Reviewed in the United States on January 11, 2017
I'm sorry to have to be the PC-police here, but does the female character, Margot, have to be so helpless? First, her hat goes missing and she has to ask Charlie to "find it for me". This damsel-in-distress cliche is reinforced by the fact that Margot is dressed as a princess and is even shown being stuck in a tower on one page. Then later in the story, when Charlie asks her "why would a princess hat be in the science lab?", Margot replies, "Because I'm desperate, Charlie!". They received a clue about the hat possibly being in the science lab, so how is the answer to that question, "because I'm desperate"? I will not be reading this to my daughter a second time.

4.0 out of 5 stars Fun with fractions
Reviewed in the United States on December 3, 2015
Cute, clever story which shows children how to identify fractions...Charlie and his family and his friend ("Charlie had 4 friends: Lewis, Henry, Scotty and Barry. Lewis was 1/4 of Charlie's friends...") are having pizza for dinner. ("Yuck, no veggies," yelled 4/6 of the pizza eaters.) But one slice goes missing and Charlie tries to solve the mystery. ("Dad was 1/5 of his suspects.") A good way for gradeschoolers to gain an understanding of how one might use fractions, and enough story here so that the little ones who don't quite get fractions will still like the book.

Humorous little interjections from the author tip a wink to the parents and the older kids: "Author's note: Anchovies are tiny little fish, and why anyone would want them on their pizza is a mystery that may never be solved." And of course, there is ****SPOILER ALERT*****stop reading if you don't want to know the ending.....it's the giveaway, the tell, the final clue.......the all-important fart joke which is vital to the plot. Farts are funny for all ages.

I'm not wild abut the retro-1950s illustrations, partly because it's a bandwagon everyone seems to be jumping on lately. Remember a few years back when suddenly there were scores of illustrations in the style of The Wild Thornberrys, all noodly limbs and tiny eyes and grommet lips with too many teeth? Now it's everyone creating characters that look like Tom Terrific. We've come across a dozen just in this week's trip to the library.

In the back of the book are a couple of pages showing a few more examples of fractions and a pizza "pie chart" with the fractions used shown all on one page. Handy, especially if you're using this book in a classroom.

Check out the video clip above to get a good sense of what the book is like.
