This video features the Louisville Slugger Museum and Factory, home to the world's largest bat. Students see the role that measurement and engineering play in making bats to professional players' specifications and are asked to consider...

In this KQED infographic, find out how much an adult in different-sized households needs to make to pay for basic monthly living expenses. In the accompanying classroom activity, students solve real-life problems involving rate and ratio...

In this video, students explore Depression-era post office murals and modern outdoor murals to learn how artists use proportional reasoning and measurement to create large-scale paintings. The video ends with the question, "How do...

This lesson will provide real world examples that involve graphing exponential functions. It is 3 of 5 in the series titled "Exponential Functions in the Real World."

Using this infographic, learn how wage equity today compares with data from 50 years ago, at the dawn of the equal pay movement. The accompanying classroom activity invites students to explore the change in the gender wage gap from 1965...

The teaching of pattern in Grades 9-12 is discussed and a collection of sites and teaching suggestions is presented.

A video presentation covering the history and evolution of statistics, as well as this area of math's link to our everyday world. View simple examples, including the application of statistics in the business world. [28:36]

In this exercise, students will learn how to find the length of one side of a polygon when the perimeter is given. Students receive immediate feedback and have the opportunity to watch a tutorial video, get hints, and try questions...

Lesson plan examines the possibility that the contemporary climate change is due to natural solar cycles. Objectives are to review the evidence of total solar irradiance, analyze data to understand the influence of solar variability, and...

In this task, students use trigonometric functions to model the movement of a point around a wheel and through space. Students also interpret features of graphs in terms of the given real-world context. Aligns with F-TF.B.5 and F-IF.B.4.

At the bottom of this page from the Georgia State University, you will two real-world applications of the Laws of Sines and Cosines (in the context of velocity vectors.)

This task provides a real-world context for examining the power of exponential growth and decay. Students experiment, at the macro level, using scotch tape to pull a chip of graphite apart into two pieces. They are asked to find about...

The purpose of this task is to give an application arising from a real-world situation, determining braking distance, in which a quadratic equation arises. For this scenario, it is natural to use a graphical method to find an approximate...

The purpose of this task is for students to find the distance between points that lie in all four quadrants of the coordinate plane. Aligns with 6.NS.C.8.

Examine some of the complexities and complications inherent in the development of a micro engine. This video focuses on how MIT researchers have to consider proportions comparing volume and surface area when factoring heat loss, taking...
