However, the conversation showed that they were guessing and then checking. In fact, they then realized, upon looking back, that they had “invented” the notion of Guess and Check. Their classmates (Natalie and Ann) found other ways to do the problem (in other words, a different “solution pathway”) and “discovered” the notion of the Make a Table strategy. Although their problem wasn’t complex, it wasn’t elementary either. They did recognize the various different approaches as there are many ways to do mathematics!
For any interior point on the grid, however, we can always reach that point by paths through the points immediately above and to the left and right of such a point. Since there is only one path from each of these points to the point in question, the total number of paths to this point is the sum of the number of paths to these preceding two points. Thus, we easily generate the number of paths from A to any given point in the grid by simple addition. In particular, there are 210 different paths from A to P, as we initially set out to determine.
A process of guessing, checking, altering the guess if it does not check, guessing again in light of the preceding check, and so on is a legitimate and effective strategy. 2 Pólya’s Problem-Solving Principles and the Standards for Mathematical Practice of the Common Core State Standards 37 doubt that a solution has been found. If we can be sure that there is only one solution, then the solution has been found. Moreover, the process is often quite efficient and may be the only approach available, although students often feel that it is not “proper” to solve a problem by guessing.
