What can you do with Scratch besides write games? Lots of math projects, secret codes, the geometry of Pi, Fibonacci numbers, prime numbers, and other sequences, and more!
One story in Frederik Pohl’s anthology Star Science Fiction # 4 is by Fritz Leiber, about a supergenius kitten named Gummitch who planned to write books explaining the world to other genius kittens. One book was to be “Space-Time for Springers,” and that is also the title of the story. My mathematical research is in number theory and combinatorics, often aided by computer explorations. Now I have grandchildren at the age of enthusiasm and wonder, one of whom introduced me to the computer language Scratch. The mascot of Scratch is a smiling ginger kitten, who might as well be Gummitch. This book uses Scratch to develop some ideas in mathematics and to invite exploration. The title makes clear the subject (mathematics) and the tool for exploration (Scratch), but in spirit it is the book Gummitch would have wanted: “Numbers for Springers.”
The aim is to keep the mathematical level of this book so that it relies at most on algebra and geometry. Even that might be a stretch for elementary school students, but there is an art to stretching without breaking that every supergenius kitten comes to know.
