 Enlarge Anno's Magic SeedsAuthor: Mitsumasa AnnoIllustrator: Mitsumasa AnnoPublisher: PaperStar Books, Penguin Putnam Inc.Copyright: 1995ISBN: 0-698-11618-6Number of Pages: 34Ohio Standards Alignment: Grades 2–7Jack receives two beans from a wizard, eats one, and plants the other. A year later, a plant grows bearing two seeds. Over time, Jack decides to plant both seeds, and the reader sees a pattern begin to emerge. However, the situation becomes more complicated when Jack decides to plant some seeds, store some seeds, sell some, and eat some. Carefully detailed illustrations make the increasingly complex scenario understandable, though still challenging. Eventually the seeds make Jack wealthy, until a hurricane wipes away all of his plants. Fortunately, his wife has saved ten seeds and they can begin the process again.Go to: How to Use This BookHighlights and InsightsRelated ORC ResourcesOhio Standards

 How to Use This Book Teachers may want to read the book to the class, discussing questions asked in the text as they go along or at the conclusion. Teachers may pose problems for partners or individuals to work on. They may simplify or complicate the problems based on the children's current mathematical development. Teachers may have children create similar problems using different contexts. Discussion would center on whether or not the same method can be used if the problem is about seeds or about some other form of growth, such as money earning a certain percent interest and either withdrawn or re-invested, or messages forwarded to 10 people on the Internet.
 Highlights and Insights Aside from the fact that there are some powerful economic lessons here, the book provides rich opportunities to develop a variety of mathematical concepts (patterns, recording data in a table, and the use of symbols to solve a problem). Children at a wide range of ages can benefit from this book. Younger children can solve problems with small numbers using manipulatives, tally marks, etc. Older children can investigate the more complex data to determine how many seeds are planted each year. Recognizing that all kinds of patterns exist in mathematics is key to mathematical understanding. Working toward finding and using patterns helps young children see that mathematics is not just a set of rules to be memorized. Older children who work with problems similar to those in the book will gain a foundation for using functions rather than doggedly struggling with individual computations.
