After refreshing Mathletes on the order of operations, the video will then focus on how to solve problems where an unfamiliar symbol is defined to be a new type of operations that follows given rules.
In this practice plan, Mathletes will recognize visual patterns and practice defining them numerically in order to find the number of elements in the pattern after a large number of repetitions.
Mathletes will become familiar with properties of 45-45-90 and 30-60-90 triangles. In this plan, the relationships between the sides of these two special right triangles will be derived. Then...
Using the commutative, associative and distributive properties, Mathletes will arrange arithmetic problems in a different order that allows them to be solved more readily.
Explore the formula d = rt by starting with unit conversion problems. Mathletes will solve for distance, rate and time by paying attention to the units given in the problem and using the appropriate...
Explore measures of central tendency, specifically mean and median, by solving common types of MATHCOUNTS problems related to sets of numbers. Use the extension at the end to develop a rule for...
Mathletes will analyze frequency tables, histograms, stem-and-leaf plots and other visual representations to solve problems about sets of data. In the extension, Mathletes will analyze a set of data...
Mathletes will explore interior angles of various polygons and understand how to find the number of sides a polygon has using information about its interior angles.
Understanding and applying ratios can be used in a variety of problems, from finding a missing measurement to determining scale between similar figures. Mathletes will solve problems using ratios...
Learn what Mass Points are and how to use them to solve problems involving side lengths and areas of triangles. Mass Points Part 1 (above) covers the fundamentals of Mass Points, while Mass Points...
