Koch Snowflake The Koch Snowflake is an example of an iterative drawing as each successive stage begins with the previous stage. The Koch snowflake begins with an equilateral triangle. The first iteration divides each side of the triangle into thirds, removes the middle third and replaces it with two line segments of the same length. Students might visualize this as constructing a smaller equilateral triangle on the middle third, then removing the original middle third line segment. Students can construct the first couple of iterations with pencil, paper and a ruler for measuring and marking each side into thirds. Koch Snowflake: Cynthia Lanius java applet that allows students to see each successive iteration of the figure [online activity] Koch Snowflake: diagrams of first three iterations in black on white background.

A function is a set of instructions for calculating a value in a spreadsheet cell. Functions consist of: data - numbers you type in the formula and values in other cells. The instructions to process that data. For example, you can write a function for each of the arithmetic operations (+, -, *, /). An equals sign always precedes any instruction. Teaching Measures of Central Tendency with Spreadsheets You can use a spreadsheet to calculate the mean and range for a set a data and determine the median and mode.
Measurement using Spreadsheets A formula can also be written to make measurement conversions. Obviously converting feet to yards is far from the only conversion. Finding Percents with Spreadsheets The example below illustrates yet another use for spreadsheets in the classroom. In order to make a table similar to the one above, it is necessary to write two formulas. Finding Areas with Spreadsheets This is a particularly powerful use of spreadsheets in the classroom.
