Are you teaching computer programming to students? This is a quarter-length curriculum to help classroom teachers teach the Scratch programming language. It contains 30 full-color, student-tested tutorials (beginning, intermediate, and advanced), including making games like Pong, Asteroids, Pac-Man, an additional "retro game," an original game, and two real-world challenge programs. Teachers who purchase either the ebook or paperback can make a class set for their students to use. Scratch is a free programming application developed by the MIT Media Lab and is available at http: //scratch.mit.edu
