The following activities deal with patterns and the importance of looking at data from more than a single perspective.
Included are explorations designed to encourage open-mindedness and to help students develop alternative viewpoints. Students investigate a series of items that appear to be ordered in some “obvious” ways. Students also explore ways of sorting items into two disjoint groups on the basis of some definable characteristic. This lesson was adapted from “What Comes Nex_?”, written by William R. Speer & Daniel J. Brahier. It appeared in the October, 1995 Teaching Children Mathematics Vol. 2, no. 2.
