As the user enters ordered pairs, the spreadsheet graphs a scatterplot, creates a line of best fit, and displays its equation (in linear or polynomial form).
Students learn about slope by experimenting with different values for "m" in the slope-intercept equation, then looking for patterns, relationships, and generalizations.
The user inputs a mathematical expression, and then alters it with parentheses to see how many different answers can be generated. Great for order of operations.
As students report measurements on circumference and diameter of objects, the spreadsheet calculates their ratio and averages them together to approximate pi.
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.
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.
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.
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.
As the user enters values for the numerator and denominator of a fraction, a circle graph is generated to show a visual representation of the fraction.
