Small Student Projects in an Introductory Statistics Course

There was a one-room school house in a remote rural area. Periodically a regional supervisor would visit the school to evaluate the performance of its teacher. On one visit the supervisor viewed a unit on the addition of fractions. The teacher wrote on the board, 2/3 + 4/5 = 6/8. After school that day the supervisor spent a great deal of time ensuring that the teacher understood the correct way to add fractions.
