- Percents and Fractions

Video by Art of Problem Solving's Richard Rusczyk.

- Algebraic Expressions and Equations
- Percents and Fractions

This plan focuses on all things percents. Mathletes will practice with tips, markups, markdowns, interest and percent of quantity scenarios. Use the 'would you rather' questions in the extension to...

- Measurement
- Plane Geometry
- Proportional Reasoning

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...

- Plane Geometry
- Proportional Reasoning

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...

- Percents and Fractions
- Statistics and Data

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...

- Sequences, Series and Patterns

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.

- Algebraic Expressions and Equations
- General Math
- Problem Solving (Misc.)

Using the commutative, associative and distributive properties, Mathletes will arrange arithmetic problems in a different order that allows them to be solved more readily.
