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.
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...
Mathletes are likely most comfortable working with numbers in base 10, but there are many other number systems to explore - other integer bases, fractional bases, and even negative bases. This plan...
