Designed to improve students' thinking, learning, and creative skills while they learn to program a microcomputer in BASIC programing language, this book for intermediate learners at the elementary school level provides a variety of microcomputer activities designed to extend the concepts learned in accompanying instructional manuals (Volumes 3 and 4). These activities require students to apply those concepts to challenging problems which need original and creative solutions. Each activity includes a program to enter, run, and observe, and a challenge requiring use of a previously taught principle. Suggestions for making changes in the program are often included. The titles of the individual activities are as follows: Custom Made; Trickery; The Right Key; Return to Sender; Author's Privilege; Immediate Math; Yellowness; Teammates; Lion Tamer; Keeping Busy; Career; Up, Up and Away; Ballooning; Random Number Generator; Little Yellow Math Helper; Squeeze; Label/List Maker; States; Game Changes-Yellow; Now You See It, Now You Don't; Character Building Exercises; Birthday Month; Toadily Dangerous; Greenness; Close Encounters; Toadily Educational; Age Gauge; How Long Ago; USA; Greatness; Ballot Maker; TLC Appearing Live; Vote Counter; Game Changes--Green; Game Maker--Green.
