Your middle schoolers will show what they know with their bodies when they become the coordinate plane in this conceptual development unit. Starting with the characteristics of the coordinate plane, learners develop their skills by...

Your favorite sports team is ranked #1. How do the powers that be determine this rating? Learn how ratings are mathematically computed using probability concepts, from the Elo Rating System for chess to the Rating Percentage Index for...

Students calculate effects of gravitational force on planets, discuss the effects of weightlessness on the human body and describe and demonstrate how objects in a state of free fall are accelerated by gravity at an equal rate.

Students demonstrate good random sampling techniques for data collection, select and develop graphic presentations of data and analyze the data to solve a problem presented.

Don't harbor any negative feelings toward negative numbers. Scholars learn about different classifications of rational numbers, including negative integers. They also develop definitions of the opposite and the absolute value of a...

The goal of this collection of lessons is to make middle schoolers more aware of the ways in which they are dependent upon water to maintain their standard of living. Learners compare water use in Lesotho to water use in the United...

Seventh graders graph ordered pairs on a coordinate plane. They create a scatterplot. Additionally, they determine the line of best fit and investigate the slope of the line. Multiple resources are provided. An excellent resource!

Students discover that proportions are made up of equal ratios each containing the same building blocks. They, using the Internet, apply their knowledge of direct relationships and proportions to problems in planetary science.

Pupils apply real data to create and calculate algebraic equations. Students create a visual to represent the concentration for one part per million and apply unit analysis to verify measurement computations. Pupils define the use of a...

Students investigate economic growth and standard of living. In this economics lesson, students investigate the GDP per capita and how it affects the economy. Students differentiate nominal and real GDP.

A collection of interactive visualizations that were produced through analysis of economic, political, and market research data. Topics are diverse, e.g., military spending and trade, immigration, consumer spending, crime, unemployment,...
