Patterns of Change: Tables and Graphs (Investigations in Number, Data and Space)

Students make tile patterns (square and triangular numbers, multiples and powers of 2) and describe how they change. They collect and express data about time and distances along a straight line with number tables, graphs, and written stories; distinguish between cumulative distance and distance between steps to identify correspondences between number tables, graphs, and stories; use Trips downlodable software to represent their steps with a meter stick and Cuisenaire rods; reflect on step size and frequency; and compare graphs of position or step size with time. Suggested pacing: 16 sessions.
