Number Balance


Two Educational Programs on cassette for the Acorn Electron

Addition/Subtraction   Multiplication/Division

This pack contains two programs on cassette. All instructions are contained in the programs and are shown on the screen. These are pictorial programs for practising simple mathematical operations for numbers 1 to 99. The object of the exercise is to make a balance level by inputting the correct missing number into one side of a simple equation. Incorrect answers will tilt the balance in the appropriate direction; after two incorrect attempts the program responds with the correct answer.

The programs offer a high degree of user control over the exercises presented the the child. 'Teachers' Notes' which appear at the beginning of each program give the user the opportunity to edit the layout, difficulty, content and timing of the exercise before the child begins. Once these parameters are set, the program can be used by up to 20 children and their results will be stored for later recall.
