This is a rather boring activity-a problem to do rather than a problem to solve. His peers did the obvious: add 1 to 2 to get 3, add 3 to 3 to get 6, add 6 to 4 and so on. But Gauss made an intuitive leap. He noticed that the sum of certain integer pairs is 101: (I +100), (2+99), (3 + 98,) (3 + 97) etc. He also saw that there are 50 such pairs of integers, so that 50 x 101 = 5050. Gauss apparently gave the answer to the teacher in less than a minute. /MCI; 4 ;/MCI; 4 ;Here's another inductive reasoning challenge: give students several subtraction problems involving odd numbers, like 7-3, 21-5, 11-9, 35-23, 57-33, etc. When investigating the results they will discover that an odd number minus an odd number always yields an even number. What about an odd number plus an odd number? /MCI; 5 ;/MCI; 5 ;Problem doing is the implementation of an algorithm, a series of steps that provide a result or answer, which the student may or may not understand. Implementing an algorithm is easy (consider a computer program which is an algorithm), but understanding the meaning, implications, answer, or /MCI; 6 ;/MCI; 6 ;process used to acquire it may be a challenge. /MCI; 7 ;/MCI; 7 ;Inductive mathematics instruction provides younger students opportunities to use intuition and to make intuitive leaps. Teaching mathematics as merely a series of algorithms that must be learned by rote and applied, sometimes haphazardly, may lead students to arrive at answers they do not understand. With the inductive process of discovery, students' intuitive appreciation of problems may be beyond their formal knowledge. Students may form misconceptions when using intuition and cling to them even when presented with new evidence that refutes them. Therefore, teachers need to help students keep their minds open so they can move from their informal insights into a more advanced stage of formal thought as required by such subjects as geometry, algebra, and calculus. /MCI; 8 ;/MCI; 8 ;Learning more about applied
