Solve word problems that involve linear inequalities in two variables. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Practice constructing, interpreting, and solving linear inequalities that model real-world situations. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Solve word problems by modeling them into a system of equations and solving it. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Determine if a quadratic or exponential model fits a data set better, then use the model to make a prediction. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

In this activity, students use the CellSheet Application to understand how to track inventory and predict future trends based on average daily use. They will collect data, analyze it and make predictions. They also learn to use linear...

This is a linear activity where the teacher and/or students collect data about the distance they live from school and how long it takes to get to school. This is a modeling activity where time is the dependent variable.

In this activity, Students can use colorimetry to determine the concentration of a colored species in a solution and use a linear relationship to model Beer's law. They use Beer's law to determine the concentration of...

In this activity, students find a conversion equation that will calculate the corresponding Celsius temperature for any given Fahrenheit temperature. Students learn to graph scatter plots, analyze and graph linear equations, compute and...

This activity can be used to explore forces acting on an object, to practice graphing experimental data, and/or to introduce the algebra concepts of slope and intercept of a line. A wooden 2x4 beam is set on top of two scales. Students...

In this activity, students fit a linear least-square regression line to population data. They explore various functions to model the given data.

This website, from the University of Edinburgh, provides a lengthy glossary of computer graphics terms written by Olin Lathrop, author of "The Way Computer Graphics Work". This site provides simple definitions of basic terms; no graphics...
