 * The Marco Polo Foundation has partnered with leading educational organizations to develop high quality Web sites to serve as resources for teachers.


 * Mean and Median
 * http://illuminations.nctm.org/ActivityDetail.aspx?ID=160
 * This applet allows the user to investigate the mean, median, and box-and-whisker plot for a set of data that they create. The data set may contain up to 15 integers, each with a value from 0 to 100


 * Mathematical Proofs
 * http://www.sciencenetlinks.com/lessons.cfm?Grade=9-12&BenchmarkID=2&DocID=0
 * In this lesson, students will explore the nature of mathematical proofs and mathematical inquiry. This lesson would be appropriate after students are familiar with the Pythagorean Theorem.
 * Product Game
 * http://illuminations.nctm.org/LessonDetail.aspx?ID=L436
 * In this lesson, one of a multi-part unit from Illuminations, students play a game in which they start with factors and multiply to find the product. The game board consists of a list of factors and a grid of products. Two players compete to get four squares in a row--up and down, across, or diagonally


 * Box Plots
 * http://illuminations.nctm.org/LessonDetail.aspx?ID=L523
 * Students will construct box plots independently. Students identify the mean, median, mode, and range of a set of data.


 * Angles
 * http://illuminations.nctm.org/ActivityDetail.aspx?ID=158
 * Students will use a simulation to explore different angles used in scoring a goal playing soccer.
