    Modern spreadsheets can make powerful mathematical concepts accessible to students at a younger age than ever before. Contours and three-dimensional graphing are topics that were previously reserved until well into the first year of college calculus. Three-dimensional graphing now can be successfully taught to middle school students with the assistance of a computer spreadsheet. This combination of the computer with hands-on activity exposes students to numerical and graphical representations of data on the same spreadsheet "page" and forces them to make connections between the two forms of data.
