This book is about a jar and all the stuff inside it. It is a multiplication book where there in the jar there is a ocean, and in the ocean there is a island, and inside the island there is 2 countries, then three mountains and so on. This helps with multiplication because they can follow along to see how many things are in the jar. Mitsumasa, the author, creates many books with different subjects. although I did enjoy this book and would have it in my class library, i do think it would be difficult for some students to get and i would not use it for a read outload.½

Sort of a surreal picture book in which inside a vase is an island, and on the island are many things, including ultimately the vase .... [return][return]A nice concept, but it didn't do as much for me as I'd hoped.

35 months - I wanted to check this one out and see if it was worth borrowing in a couple years for understanding multiplication. Not bad. The illustrations give visual understanding to a concept that can often seem too abstract to kids.

Anno presents a jar with the ocean in it. In the ocean we find an island. Everything on the island is in multiples. We then see that at the end that there are 3,628,800 jars in the original jar. The author represents the multiples on the remaining pages of the book. He shows the reader that 180 more pages filled with dots would be needed to represent the final number of jars. The author emphasizes the patterns evident in this book with the concept of factorials.

This book could be used as an introduction to the concepts of multiples. One could read this book aloud with a class to activate prior knowledge or build knowledge on the concept. One could also use this book for factorials and representation as well.

This book attempts to explain factorials to students with a magically jar that has a world in it. The world breaks into multiple different scenarios where the number of objects get larger. I find the book becomes confusing because at the end if tries to explain the problem and makes it more difficult. I have taught this concept before and the way the book explained it made me confused. I would not recommend reading this book to help understand factorials better.

This is a good book to teach students about factorials. It is also a nice tool to explain to students that there may be times that short cuts can be used in math.

This story begin with 1 jar and then when we look inside this jar we find 2 countries each with 3 mountains with 4 walled kingdoms, 5 villages, 6 houses, 7 rooms, 8 shelves, with 9 boxes and 10 jars where the cycle repeats again. The author then uses dots to represent this concept in order to explain how quickly things multiply. The main concept in this book is factorials. Having used this book in lessons, I have had the students actually calculate the number of mountains in 1 jar. Then the number of walled kingdoms, villages, etc. The students are able to demonstrate the concept of factorials.

A picture book about factorials! This story illustrates how numbers multiply by showing objects nested inside each other. We start with one island, and on the island there are two countries, and in each country there are three mountains, and and so on until we finish with ten jars (10!) inside a box in the cupboard of a room in a house in a village within the walls of a kingdom on a mountain in a country on an island. (whew!)
After the pictorial story, we learn the mathematical explanation by substituting the pictures for dots. The story is illustrated with finely detailed watercolors. It's an excellent example of a picture book most appropriate for older children (grade 4+)

Sort of a surreal picture book in which inside a vase is an island, and on the island are many things, including ultimately the vase ....

A nice concept, but it didn't do as much for me as I'd hoped.

Book Summary: this book uses a jar and many things in it to represent factorials. It starts with a jar that contains 1 island that has 2 countries that has 3 mountains that has 4 walled kingdoms that has 5 villages that has 6 houses that has 7 rooms that has 8 shelves that has 8 cupboards that has 9 boxes that has 10 jars. It then represents this concept with dots to show how things can quickly multiply.

Content Summary: factorials, multiplication

This is a good example of an informational fantasy, because in order to enter the world of this "mysterious multiplying jar," the reader must set aside skepticism and the way things work in our world. However, the authors use a fantasy-type journey to teach students accurate information about factorial numbers in a simple and easy-to-understand way.

Illustrations: watercolor and ink (?)

(I did not give it a rating, because character and plot, etc. are not applicable in informational books)

Media: pen, ink, watercolor
Genre: Informational
Age Appropriateness: Intermediate and Secondary (probably just first half)

Delightful way to introduce the idea of factorials to children.

What a great way to visualize the power of multiplication without overwhelming a child. We first read this book when my child was about five years old and now as he's working on multiplication in math we will revisit the magic jar.

A very neat book book that visually explains factorials.

FROM BACK OF BOOK:
Inside Mr. Anno's jar is not a genie but a deceptively simple bit of water, which leads somewhat magically to the deeper waters of the sea, and thence to a series of amazing numerical happenings.

Fine condition
