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 junior high level provides a variety of microcomputer activities designed to extend the concepts learned in the 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 principle taught in the related instructional manuals. Changes to clarify the use of a new principle are included for some projects. Activities include: creating programs that ask for the first name of a person to be guessed; print on the screen only those numbers that can be divided evenly by 7; store random numbers; store 5 random integers in an array; print all the whole numbers from 1 to 10 and print a star next to those numbers that are even multiples of 3; print the message EVEN or ODD after each number from 1 to 10; and display a small spaceship on the screen. A final superchallenge asks students to create and save several subprograms that can be combined to form the start of a game. (Author/LMM)
