Line Graphs and Commercial Costs

A line is a line is a line. As a middle school assessment task, learners first identify graphs of given linear equations. They then identify the equations that represent real-world situations.

This activity helps young mathematicians connect the graph and the point-slope form of a line, by first solving a real-world problem and then using that example to motivate the understanding of the equation. By manipulating the gizmo,...

Pre-algebra protégés critique a graph depicting Tom's trip to the bus stop. They work together to match descriptive cards to distance-time graph cards and data table cards, all of which are provided for you so you can make copies for...

Sixth graders compare and contrast bar and line graphs. Using a weather forecast of the area, 6th graders record the high and low temperatures in a table. Students determine and justify the most appropriate graph to display a given set...

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...

Scholars create colorful bar, line, or pie graphs. They decide on a survey question to ask or a type of data to gather. From there, they collect information and data. They display this data in bar, line, or pie graphs that they create...

Y equals graphs are horizontal, but x equals graphs are vertical. Learners explore the connection between the graph and the equation of vertical lines while watching an instructional video. The presenter shows a set of ordered pairs...

Evaluate the steepness of lines, also known as the slope, by watching this video. A tutor explains what the slope of a line is and compares 2 different lines to demonstrate slope. A practical introductory video for classes that are just...
