Getting to Know Hopscotch [PDF ebook] 

Hopscotch is a block programming language designed for the Apple i Pad and i Phone that makes learning about code accessible, exciting, and fun. Because coders drag blocks of code to write programs, they can learn the major concepts of coding without having to struggle with the syntax, special vocabulary, or even the typing of text required in text-based languages. In this instructive resource, coders will learn how to create drawings, simple animations, or games they can share with others, and they can have fun doing it.
