9th Grade Math Proficiency Test

Lesson 1: Using Standard Deviation, part 1 - The student should have a knowledge of how the mean and standard deviation of a set of numbers is calculated using a scientific calculator. It is preferred that they know how to get the standard deviation without using the statistical mode in the calculator. Their insight into the uses for the standard deviation will be more complete if this is so.

Lesson 2:Using Standard Deviation, part 2 - This lesson is planned as a follow-up to "Using Standard Deviation: Part 1." The student should understand how to use the standard deviation and percentage error to decide if a set of numbers are consistent or not.

Calculating Car Payments - The student will use a formula containing complex fractions and large exponents to calculate a monthly car payment.

Statistics"Prisoner's Dilemma" (Axelrod, 1984) - The two players in the game can choose between two moves, either "cooperate" or "defect". The idea is that each player gains when both cooperate, but if only one of them cooperates, the other one, who defects, will gain more. If both defect, both lose (or gain very little) but not as much as the "cheated" cooperator whose cooperation is not returned. The whole game situation and its different outcomes can be summarized by table 1, where hypothetical "points" are given as an example of how the differences in result might be quantified.

Graph Theory through games that can be played on a table or on the playground. Graphs are mathematical objects that are made of dots connected by lines. Graph Theory is the branch of mathematics that involves the study of graphs. Graphs are very powerful tools for creating mathematical models of a wide variety of situations. Graph theory has been instrumental for analyzing and solving problems in areas as diverse as computer network design, urban planning, and molecular biology. Graph theory has been used to find the best way to route and schedule airplanes and invent a secret code that no one can crack.

Map Coloring - Coloring is a profound mathematical topic with many multi-million dollar industrial applications. The problem presented here has been of interest to mathematicians for over a hundred years. Some versions of the problem are easy to solve, others have yielded only recently to relentless efforts that would not have been possible without the aid of powerful computers. In all of its aspects, the basic problem is the same: How many colors do you need? With a few crayons or markers and some hand-drawn maps, children can quickly find themselves grappling with some of the same conundrums that contemporary mathematicians do. Four-color map problem.
