Also, try sketching on the six included Draw-Your-Own strips. The included instruction booklet provides a history of this classic invention, explains how it works, and tells you how to bring your own drawings to life.

Recommended book: *You Can Count on Monsters*

Using a unique teaching tool designed to motivate kids to learn, this book visually explores the concepts of factoring and the role of prime and composite numbers. The playful and colorful monsters are designed to give children (and even older audiences) an intuitive understanding of the building blocks of numbers and the basics of multiplication. The introduction and appendices can also help adult readers answer questions about factoring from their young audience.

### For young creators with big ideas:

Recommended book: *The Hitchhiker’s Guide to the Galaxy*

Seconds before the Earth is demolished to make way for a galactic freeway, Arthur Dent is plucked off the planet by his friend Ford Prefect, a researcher for the revised edition of The Hitchhiker’s Guide to the Galaxy, who has been posing as an out-of-work actor for the last fifteen years. Together this dynamic pair begin a journey through space aided by quotes from The Hitchhiker’s Guide, which claims, among other things, that 42 is the ultimate answer to life, the universe, and everything. Is there math in this whimsical odyssey, or is it math fiction?

### For puzzling teenagers:

Perplexus

Perplexus is the original challenging 3D Labyrinth contained within a sphere! Inside the Perplexus, you’ll face 22 feet worth of challenging twists, turns, and obstacles! Flip, twist, and spin Perplexus to move the ball along the numbered path. If you fall off the track, just head back to the start and try again.

### For adults who love twists and turns:

Frabjous

Frabjous is both a sculpture and a geometric assembly puzzle. Made of thirty identical pieces, the planes of the shape are the face planes of a great rhombic triacontahedron, a self-intersecting polyhedron with thirty rhombic faces.

Recommended book: *Programming for the Puzzled*

This book builds a bridge between the recreational world of algorithmic puzzles and the pragmatic world of computer programming, teaching readers to program while solving puzzles. Puzzles are real-world applications that are attention grabbing, intriguing, and easy to describe. Each lesson starts with the description of a puzzle. After a failed attempt or two at solving the puzzle, the reader arrives at an Aha! moment—a search strategy, data structure, or mathematical fact—and the solution presents itself. The solution to the puzzle becomes the specification of the code to be written.

### For seniors with infinite ideas:

SET Card Game

Keep your reflexes sharp with SET, one of the most award-winning games of all time. Race to find as many SETs as you can—the player with the most SETs at the end of the game wins.
