Anno’s Mysterious Multiplying Jar
By Masaichiro and Mitsumasa Anno
Paperstar Books (1982) ISBN: 069811753
This elegant picture book captures the imagination with its whimsical illustrations and the story about what’s inside a jar. It begins with simple jar that holds a “wide, deep sea.” The reader follows the journey of a boat to an island and learns all its contents. At first the reader gets pulled into the story and sees this pattern of growth. Midway, the narrative is interrupted and shifts into a mathematical explanation of factorials. The authors show how the narrative connects shows how factorials work.
Quantitative: Lexile Level--AD320L ; ATOS--N/A
Qualitative: This book is appropriate for any math level looking to understand factorials. It would best serve students in middle grades due to content; however, the shift in storyline, the connection of narrative to math, and the lengthy description of factorials at the end, make this a complex text that a teacher would have to read and explain to his/her students.
Content Area: Math--Multiplication; Math--Factorial; English Language Conventions
Curriculum Suggestions: The book directly connects to math. To go beyond just concepts, teachers could have students create their own factorial stories to demonstrate their understanding of the concept. They could use Anno’s Mysterious Multiplying Jar as an example for their own factorial (or other math concept) narrative.
Another thought is that teachers could also use the book to explain prepositional phrases. In the narrative portion of the text, all the sentences begin with “on” or “within.” It could be a way for teachers to demonstrate how prepositional phrases are used across all disciplines.
Common Core Standards: RI 6.2; Language 6.1, 3.
Common Core Math Standards Grade 7:The Number System
Apply and extend previous understandings of multiplication and division and of fractions to multiply and divide rational numbers.
a. Understand that multiplication is extended from fractions to rational numbers by requiring that operations continue to satisfy the properties of operations, particularly the distributive property, leading to products such as (–1)(–1) = 1 and the rules for multiplying signed numbers. Interpret products of rational numbers by describing real-world contexts.
b. Understand that integers can be divided, provided that the divisor is not zero, and every quotient of integers (with non-zero divisor) is a rational number. If p and q are integers, then –(p/q) = (–p)/q = p/(–q). Interpret quotients of rational numbers by describing real world contexts.
c. Apply properties of operations as strategies to multiply and divide rational numbers.
d. Convert a rational number to a decimal using long division; know that the decimal form of a rational number terminates in 0s or eventually repeats.

Personal Thoughts: This book presents a fun, new way to learn math and shows how math can easily display a narrative. Anno’s Mysterious Multiplying Jar would be an excellent resource for the CCSS that ties into English and math in meaningful ways
*Meets the “Math Picture Book” requirement
