instructions had to be doable andunambiguous. As the students quickly learned, even when the solution to a problem is wellunderstood, it is sometimes difficult to express the solution in elementary steps.The class then built on the idea of the kind of steps needed in an algorithm by writinginstructions for an imaginary S robot. The S robot was defined to be able to pick up one playingcard from a deck and hold it in its hand. It could make some determination about the card such asits suit or value and it could either put the card back on the top of the deck or discard it to thefloor. The students were again placed in groups, given some playing cards, and assignedproblems to solve of the nature: count the number of cards in the deck. New instructions

In this method a rather long base line ismeasured on one coast, say 25 miles, using a steel tape and taping bucks6. Using a transit toensure that the line is straight and leveling to determine the elevations of the ends of the tape, avery precise measurement is made of the base line (a very long and tedious task). See Figure-2on the left is a metric leveling rod, in the center a taping buck. The elevation of the end points ofthe tape are determined with dumpy level as shown in Figure-3.
