First of all, congratulations! And thanks! After a successful crowdfunding campaign, *Ying and the Magic Turtle* is published and available. In that story book, readers experience mathematics, problems solving, and the rewards that come with perseverance. Children ages five and up, parents, and teachers can enjoy this retelling of an ancient legend for its rich beauty in mathematics.

### Five Fabulous Activities – crowdfunding ends February 29

Next up! Tenth book to be published by Natural Math, *Five Fabulous Activities for Your Math Circle*, is up for crowdfunding!

A math circle is any group of people gathering to explore mathematics—it could be in your home, in school, or even online. Math circle activities are often interactive, exploratory, flexible, open-ended, and social. How does one make it happen? *Five Fabulous Activities* * *by Samuel Coskey, Paul Ellis, and Japheth Wood, veteran math circle leaders, will help show you how. This book is a guide and a collection of recipes for anyone who wants to help others discover joyful and challenging math.

The book is primarily for middle and high school students. Each chapter also includes activities and explanations intended for younger math friends. The underlying mathematics can be of interest even to adult learners, including the authors!

The funding campaign quickly reached its goal. At the current stretch goal, for every $100 we raise, we will donate a copy of the book to a math circle serving groups of people who are underrepresented in STEM fields.

Our math friends shared these function machines. Can you guess what they do?
