What Happens on Average
Fifth graders are introduced to convergence of sequences based on averaging previous terms in the sequence. The power of the "fill-down" function in spreadsheets is exploited. By using various starting numbers, and inferring the limit,...

Isotopic Pennies
Many people confuse atomic mass and atomic numbers. The sixth of seven lessons in a unit requires scholars to find the weight of different groups of pennies. Then, they must solve how many of each type of penny exists in a closed system...

The Bigger they Are . . .
Students do a variety of data analyses of real-life basketball statistics from the NBA. They chart and graph rebounding, scoring, shot blocking and steals data which are gathered from the newspaper sports section.

Mean, median, and mode... Use the data
Ninth graders participate in a lesson focused on the concept of basic statistics. They find the mean, median, and mode of different data sets. More advanced students could practice creating a bell curve from the data.
