Funville Adventures

Funville is a math-inspired fantasy adventure by Sasha Fradkin and Allison Bishop, where functions come to life as magical beings.  After 9-year old Emmy and her 5-year old brother Leo go down an abandoned dilapidated slide, they are magically transported into Funville: a land inhabited by ordinary looking beings, each with a unique power to transform objects.

Stories and interviews

“You too will want to visit Funville, a delightful land where magical and strangely mathematical powers run rampant!” – Jordan Ellenberg, author of How Not to be Wrong

“Mathematical words can sound scary, but the concepts they describe are not: Funville Adventures proves this so!” – James Tanton, MAA Mathematician at large

“Enjoy the story. Stay for the math. Emmy and Leo’s magical adventure will encourage families to play with ideas together.” – Denise Gaskins, author of Let’s Play Math series

As Emmy and Leo explore this exciting new world, befriending many Funvillians along the way, they discover that despite being able to do some very impressive tricks with their powers, Funvillians often get stumped by situations requiring more than just the straightforward use of a single power. Emmy and Leo think outside the box to solve problems by using combining multiple powers, as well as using ideas that do not involve powers.

While on the surface, Funville Adventures is just a fairy tale, the powers of the Funvillians are a vehicle for introducing children to the concept of a function. Each power corresponds to a transformation such as doubling in size, rotating, copying, or changing color. There is even a Funvillian whose power is to change other Funvillians’ powers. Some Funvillians have siblings with opposite powers that can reverse the effects and return an object to its original state, but other powers cannot be reversed. In this way, we introduce kids to the mathematical concepts of invertible and non-invertible functions, domains, ranges, and functionals without mathematical terminology.

The concept of a function is truly fundamental, and accessible to children from a young age. It is unfortunate that for many of them, their first encounter with it is in high school or late middle school, often in a dry, technical manner. We present this material in a form that will appeal not only to kids already interested in math, but also to who are missing out on mathematical adventures.

Meet the Authors

Dr. Sasha Fradkin has loved math from an early age, and seeks to share that love of math with others. After receiving her PhD in mathematics from Princeton University, she worked for several years as a professional mathematician and taught enrichment math at the Golden Key Russian School to children ages 4-10. Last year, Sasha became the Head of Math at the Main Line Classical Academy, an elementary school in Bryn Mawr, PA. She develops their math curriculum and teaches children in grades K-5. She writes a blog about her teaching as well as various math adventures with her two daughters, and enjoys pondering about exciting and engaging ways to present the beauty of mathematics to young children.
Dr. Allison Bishop grew up with a passion for writing, and initially disliked math because it was presented as formulaic. She belatedly discovered the creative side of mathematics and science, and now sees it as a vital component of the curiosity that drives her life. She is currently a professor of computer science at Columbia University as well as a quantitative researcher at the Investors Exchange. She remains an avid fiction enthusiast and writer, and is always seeking new ways to expose young minds to creative mathematical thinking and fuel their scientific curiosity.

Meet the Publisher

nm_logo_100pxAs a parent, teacher, or math circle leader, you want books that are helpful for your children. Will the book make sense? Will it add rich and beautiful math to your child’s life? Will it be fun? So that you can say YES to all of these questions, the Natural Math community has developed a unique publishing process.

A quality book takes professional artists, editors, and designers – we got them! Yet great books start with dedicated authors who care enough to spend dozens of hours improving each little activity by testing it with many children, families, and classes. Then early drafts go through revisions when authors of other books help to refine the new project. This is more work and nurture than most math books ever get, but we are not done!

Next, we invite beta readers – brave community volunteers who field-test the draft in their own families and classes, without the authors on-scene to help. Our beta readers are new parents and veteran homeschoolers, principals and classroom teachers, leaders of first-time math playgroups and long-running math circles. They come from all learning backgrounds and all continents (except Antarctica). Readers tell us where to add examples, which activities need more ‘wow’, which terms to explain, and what children’s questions were tough to answer. That’s how Natural Math books become so real. 

And One More Thing

Our book is published under Creative Commons license. It means that people all over the world can access its content, translate it into different languages – and share their ideas based on the book with you.
