SA and NT: Stacking Bricks

by Texas Instruments

Overview

This activity presents a real-world situation--stacking bricks in a pile--that can be modeled by a polynomial function. Students create a small table to show how the number of bricks relates to the number of rows, and calculate the first, second, and third differences of the data. Next they use the graphing calculator's statistical calculation functions to perform the correct regression. Finally, they evaluate the model using a variety of methods.

    Students start by determining the number of bricks in a stack with 1, 2, 3, 4, 5, and 6 rows. Then they will calculate the successive differences and record the values in the table on the worksheet. Students also need to enter the data for L1 and L2 in the calculator.
