__Assigning Student Numbers Passage One__

Mr. Davis is an eccentric teacher who likes to get to know his students before he learns their names. He has a special set of

poker chips on which he has painted the numbers 1 – 50 (as he has never had more than 50 students at once). He keeps the

chips in numerical order so that he will be able to quickly determine if any go missing. He secures them with two rubber

bands, one in each direction, and keeps them in his desk drawer.

__Assigning Student Numbers Passage Two__

On the first day of school, Mr. Davis stands in his doorway and greets his 23 new students with a hearty cry of, "Greetings!

Please don't say anybody's name today! I'll learn more about you next week." As he greets them, he tosses each student a

numbered chip from the top of the stack, in the order in which each student arrives. For the first week of school, students

are addressed only by their numbers, which they place face up on their desks. At the end of the first week, Mr. Davis asks

his students to introduce themselves to the class using the chips to determine the order of presentations. He writes the

students' names next to their numbers for his own records. He recollects and orders the chips, and stores them away for

next year.

__Assigning Student Numbers Passage Three__

In the spring, Mr. Davis wants to display the results of the midterm and the final exam graphically and he wants his students

to understand where they are in the distribution. He decides to use their student numbers to identify them, hoping that

students will remember their own number but not everybody else's. Here is the result:
