Animation Type: White Board. Original Handbook Problem: The circle shown has a diameter of 12 inches, m<ABC = 30 degrees and AB = BC. What is the length of minor arc AC? Express your answer in terms...
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...
