Graphing the Past Using Today's Technology

Solve problems using a variety of problem solving strategies involving two variables. In this algebra lesson, the pupils add, subtract, multiply, and divide to solve linear equations. They graph their lines using slopes and intercepts.

Middle-schoolers graph data. In this color of money lesson, mathematicians use graphing calculators to input given data. They display the information as a regression line and as a scatter plot. Pupils identify the linear equations they...

How can digital technology of today link us to the events of the past? Scholars use technology to uncover the vast number of historical resources available in lesson 12 of a 22-part America's History in the Making series. Using databases...

Once you know how to graph y = b^x, the sky's the limit. Young mathematicians learn to graph basic exponential functions and identify key features, and then graph functions of the form f(x) = ab^(x – h) + k from the function f(x) = b^x.

Graphing points is like painting a picture in algebra. Starting with a number line, the video constructs the coordinate plane. The presentation introduces the concept of a coordinate pair as an intersection of the two lines containing...

Help learners recognize the characteristics of a quadratic graph and how changes affect them. An informative video uses a graphing calculator in order to find out what happens when the leading coefficient of a quadratic changes. The...

Eighth graders research statistical data regarding their current social studies unit. They write questions about the measures of central tendency, collect and analyze the data, insert the data into a spreadsheet, and generate graphs.

Here are a set of graphing lessons that have a real-world business focus.  Math skills include creating a scatter plot or line graph, fitting a line to a scatter plot, and making predictions. These lessons are aimed at an algebra 1 level...

It may be startling to know that the same bacteria responsible for the Bubonic Plague in the mid-fourteenth century still exists today. But don't worry, this video examines the causes and effects of the Black Death, and why the disease...

Break out the calculators to graph linear equations. After a review of how to rewrite an equation in slope-intercept form, give the class various linear equations. They will put the equation in slope-intercept form, and then use this to...
