Integrating Spreadsheets in the Math Classroom 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 (+, -, *, /). 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.
How to Become a Pure Mathematician (or Statistician) School:Mathematics Welcome to the School of Mathematics! The Lorenz attractor is a chaotic map, noted for its butterfly shape. The map shows how the state of a dynamical system evolves over time in a complex, non-repeating pattern. The attractor itself, and the equations from which it is derived, were introduced by Edward Lorenz in 1963, who derived it from the simplified equations of convection rolls arising in the equations of the atmosphere. Since you're here, you either are someone wishing to share your knowledge of Mathematics, or you are someone who wishes to gain knowledge about Mathematics. Mathematics has many facets; though it has a wealth of applications, Mathematics is also a science, and an art, in its own right. The School of Mathematics is a work in progress. The School of Mathematics wishes you a very warm welcome. Divisions and departments[edit] Divisions and Departments of the School exist on pages in "topic" name space.

Winter Math Activities 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. 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. Penguin Math Build on students' natural fascination with penguins by including these math pattern activities: Pascal's Penguins - 1 introduces primary students to a small version of Pascal's Triangle in this simple patterning activity.

Purplemath Modern X-ray technology reveals Archimedes' math theory under forged painting Stanford Report, August 9, 2006 Archimedes Palimpsest Project Bergmann, left, and Noel place fragments from the Archimedes Palimpsest in front of the X-ray beam. A scan of the palimpsest reveals vertical text hidden beneath the paint. Multispectral imaging revealed that Archimedes was well on his way to developing calculus, nearly 1,000 years before Isaac Newton. After more than 1,000 years in obscurity, the last unreadable pages of the works of ancient mathematician Archimedes are being deciphered, thanks to the X-ray vision at the Stanford Linear Accelerator Center (SLAC), which Stanford operates for the U.S. "It is amazing how much the Archimedes Palimpsest project has gained from Stanford University," said Will Noel, curator of manuscripts and rare books at the Walters Art Museum in Baltimore, where the document is housed. The manuscript uniquely records several of the works of the legendary 3rd century B.C.E. mathematician, who famously exclaimed "Eureka!" Archimedes rediscovered
