Fourth graders use the story of the discovery of irrational numbers to explore the different classes of numbers, the different ways in which numbers may be represented, and how to classify different numbers into their particular class.

Eighth graders pick a topic or person to research related to the history of mathematics. They brainstorm and create a concept map, using the multimedia software inspiration, about what they are researching and want to examine. They then...

Learners determine the number of laps a driver would need to complete the Indy 500. They calculate the length of time it would take to complete the race at different rates of speed.

Let's paint the town equal parts yellow and violet, or simply brown. Pupils calculate the amount of blue and red paint needed to make six quarts of brown paint. Individuals then explain how they determined the percentage of the brown...

Have you ever been told that your new car begins to lose its value as soon as you drive it off the lot? Aspiring accountants take on the concepts of depreciation and book value through an easy-to-deliver career and technology lesson. The...

Students explore approximate and exact solutions. In this interdisciplinary lesson, 6th graders will be placed in 'family groups' to create a budget that is subject to random events as chosen from the 'things happen' box. This lesson...

Win the war of the worlds! Scholars solve a variety of problems related to an alien invasion. They determine where spaceships have landed on a coordinate map, devise a plan to avoid the aliens, observe the aliens, and break a code to...

Second graders become familiar with need strategies for computation of money problems and estimating sums. In this computation lesson, 2nd graders solve real life problems to understand estimation and money problems.

Through a variety of physical and theoretical situations, learners are led through the development of some of the deepest concepts in high school mathematics. Complex numbers, the fundamental theorem of algebra and rational exponents...

Eighth graders discover the relationship between speed, distance, and time. They calculate speed and represent their data graphically. They, in groups, design a ramp for their matchbox car. The goal is to see who's ramp produces the...

Students define fractals and patterns. They explore how a seemingly random process can result in a pattern. Students practice probability and fractions skills by playing the chaos game online.

Students, in teams of four, practice shooting free throws while mentally converting the ratio of shots made to those thrown into a percent. They chart and record the ratio, decimal and actual percentage earned after each round.

In this interactive, students use logic to solve three riddles involving a frog jumping contest and then place the contestants' jumps at the correct points on the number line. Numbers are randomized so that the frogs' placements on the...

In this interactive, use logic to solve riddles involving flea circus high jumps. Then, add two consecutive jumps and place them on a vertical number line. This often requires you to find equivalent fractions with common denominators....

In this exercise, students practice rounding decimals using a number line. Students receive immediate feedback and have the opportunity to get hints and try questions repeatedly.

Practice using a number line to round decimal numbers. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.
