There are 20 different mystery formulas in this spreadsheet. For each one the student enters several numbers for the "Input" and examines what comes out for the "Result", trying to determine each function by looking for patterns.

Two different bar graphs are made from the same survey of favorite foods. The students need to determine which graph is more fair and why, by studying the graphs and altering the data.

Three different sets of data (earnings, votes, heights) are shown with three different types of graphs (line, bar, circle). The student is to compare the different graphs to determine which is the best representation.

The student enters data and then the spreadsheet generates several measures of that data such as mean, median, mode, quartiles, and range, which the user can investigate and compare.

As students report measurements on circumference and diameter of objects, the spreadsheet calculates their ratio and averages them together to approximate pi.

A generic 8 item pie chart can be dynamically altered with custom data and labels.
