Early Learning III: Early Subtraction II Early Subtraction II teaches subtraction with the numbers placed horizontally across the screen. The program will drill the student on numbers from 1 to 9. The teacher can optionally select numbers from 0 to 20. On the lowest levels, a number of objects are presented on the screen for the student to count. After determining the number of objects, the student types the answer on the keyboard. Some of the objects are moved away and counted again. Finally, the remaining set is counted. As the program progresses, the "-" sign and "=" line are introduced and the clues are gradually taken away until the student is solving equations on the screen with no objects to count. Digitized speech guides the student through each problem. The teacher can choose whether the program uses the words "minus" and "is", "minus" and "are" or the words "minus" and "equals". |
