Missing Signs


This pack contains three programs on cassette. Select the number of the program you want to load, and press RETURN. All instructions are shown on the screen. PUT IN THE SIGNS provides practice in addition, subtraction, multiplication and division. Each exercise presents the pupil with incomplete sums into which they must insert the sign which will make the calculation correct. If two incorrect attempts are made, the program provides the correct answer.

The two Missing Signs programs present addition and subtraction, or multiplication and division equations which have the balancing sign missing. The child must calculate both sides of the equation and decide whether the missing sign is greater than (ie >) or less than (ie <) or equal to (ie =). The equations contain one or two digit numbers. All three programs offer a high degree of user control over the exercises presented to the child. The "Teachers' Notes" give the user the opportunity to set 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.
