Graphing the Past Using Today's Technology

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

Graphing calculators make solving systems of equations a cinch. Individuals graph systems to locate their solutions. They also learn about situations when there are no solutions and when there are infinitely many solutions.

Young mathematicians first graph a series of quadratic equations, and then investigate how various parts of the equation change the graph of the function in a predictable way.

Middle-schoolers graph data. For 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...

Determine a solution through accurate graphs. Using 2 examples, the narrator walks viewers through the steps to graph a system of linear equations to find the solution. 

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...

Take the tediousness out of graphing. Using the interactive tool, learners can efficiently create a line graph from a set of data. They then use the graph to answer questions about specific trends in the data.

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...
