Slopes and Rate-of-Change

In this algebra I/algebra II instructional activity, students determine the function that expresses the rate of change for the given situation. The two page instructional activity contains thirteen multi-step problems. Answers are included.

Rate of change isn't found only in a classroom but in everything that fluctuates. Show your learners they can find the rate of change in real-world situations with examples using time and temperature. The video starts by reviewing how to...

Introducing slope as "a way of measuring the inclination of a line," Sal endeavors to provide a working knowledge of slope problems and problem solving. The video is framed as a review, but could be a good way to fill any holes in...

This video demonstrates everything about slope as it goes through a variety of examples depicting rate of change in more than just linear graphs. Show your learners that slope can be found in the world around them, such as in race times...

Find slope all around us and calculate the rate of change during this video that uses real-life situations. Your learners will start by creating a table to see how each change creates the pieces of slope. Plug that slope into your...

With math all around us, your learners will see they can create an equation to model different situations. From fundraising to a cell phone plan, your mathematicians can find the starting point b, plug in the rate of change m, and create...

Rates of change can be a slippery slope. The resource makes the connection between the rate of change and the slope of a line. It continues on to provide examples of how to interpret the slope and the y-intercepts of linear equations...

Graphs tell a story, and in this activity learners explore different graphs.They analyze slope and rate of change from the graphs and answer questions about the information they represent. This lesson even contains extensions for more...

The instructor uses a graph representing time and distance to illustrate how to solve this word problem. She explains each step: rate of change, distance, time, vertical change over horizontal change, change in distance, and change in...

The rate of change is defined as how one quantity changes in relationship to another quantity. The instructor diagrams a graph and demonstrates how to use a formula to calculate the rate of change. It might take two viewings to catch all...
