The Number of 2-Element Subsets of a 100-Element Set: Seventh-Grade Solutions
Keyword(s):
In the new programs section of the October 1973 edition of the Mathematics Teacher is an article describing the Comprehensive School Mathematics Program (CSMP). The secondary school portion of the program is written for bright, verbal, well-motivated junior and senior high school students. Last year I observed a seventh-grade class at Burt Junior High School in Clarksville, Tennessee, where these materials (Elements of Mathematics, Book O)were being used. On that particular day the class was studying subsets. The assignment from the previous day included a problem where the students were to find the number of 2-element subsets that a 100-element set has.
