This is one of the few programs in this book which does not employ the database, but draws its educational value from the user learning to estimate the sum of a group of numbers. There are five levels of play with level 1 being the easiest, and up to five people can play. As the game progresses, your horse will move by a distance which depends on the accuracy of your estimate. The maximum you can move is 100 places and the minimum is 0. Instructions When executed the screen will show the track, the five horses and the crowd which has assembled to enjoy an afternoon's sport. The computer will ask you what level you require and the response should be a number in the range 1 to 5 (1 is the easiest and 5 the most difficult). Next the computer will enquire about the number of players and again you will have the choice between 1 and 5. After this you are asked to input their names, and then a brief résumé of the instructions is displayed. The game now begins with each player in turn being shown a mathematical problem for which they must estimate the answer. After ten seconds the problem disappears. Although there is now unlimited time in which to decide on an answer, it is very difficult to retain enough information in your memory to use this time effectively. The race is won by the first person to reach the finishing post and then the computer offers you the choice of having another game or putting an end to the day's racing. |
