Recommends it for: children starting to read chapter books
This is another interesting story in the Horrible Harry series by Suzy Kline and Frank Remkiewicz. We've read several of the books in this series and found them to be funny, short, and entertaining.

I love that this book introduces children to the Fibonacci sequence of numbers. The explanation is interesting and is woven so neatly into the story that children might not even notice that they are learning something new! I also like that Harry figures out the sequence, but does not use this knowled
This book was simple, yet fun. I loved the math it included, because it was interesting for my children to try to figure out the Fibonacci sequence. My children found the first chapter to be funny. They have enjoyed all of the books we've read it this series so far. They are very easy to read.

Harry acts as a detective througout the book to tyr and solve the math mystery of who will win the contest before he gets tattled on. I liked this story. If these stories were around when I was in gradeschhol,I would have loved to read them. I like books about adeventure and thrill and this book definateley keeps you guessing throughout. It is filled with suspence. It would be a great read for grades 3-6.

This is a story about Harry, his friends, and his teacher trying to crack a code that seems like a mystery, but isn`t. Other wise, it would be on my 'Mystery' shelf. Horrible Harry`s 'mystery' is a lunch code. Harry know there`s a new lunch rule so he guesses who`s going to find the thing, that the rule is.
Horrible Harry is another popular series. The books are written from an elementary school-aged kid's perspective. Readers relate well to the happenings and will look forward to reading more of the books. These books are available in downloadable audio from our website,
Horrible Harry is determined to be the best detective. Harry has decided to try and figure out the mathematical code so he can win the contest in the cafeteria. I would use this book in the classroom to show Harry's determination and adventures.

What can I say? Any book that teaches the Fibonacci Sequence to 7 year olds is just awesome.
