Original Handbook Problem: Given the points A(–2, 1) and B(3,4), what are the coordinates of point C in the fourth quadrant such that m<CAB = 90 degrees and AB = AC? Express your answer as an ordered...
Winner of the 2012-2013 Math Video Challenge. This video was created by the Soda Fountain Team. The Math Video Challenge is an innovative program involving teams of students using cutting-edge...
The distinct letters from the word MEMORIAL are used to create set Z, such that Z = {M, E, O, R, I, A, L}. The letters from the word DAY are used to create set Y, such that Y = {D, A, Y}. If set X is...
This plan will help Mathletes to develop a strategic approach to counting the occurrences of a certain shape in a more complex figure made of multiple intersecting lines.
This plan builds on what Mathletes already know about ratios to introduce the definition of probability as a ratio of desired outcomes to total outcomes. Mathletes will then practice calculating the...
Explore combinatorics by looking at a common type of MATHCOUNTS counting problem – counting paths between two points. End with an extension that connects counting paths to another type of combinatoric...
This plan will introduce Mathletes to The Fundamental Counting Principle – a faster method to determining the total number of possible outcomes of an event without listing them all out!
