Slopes and Rate-of-Change

Given a graph of earning for supervising children at a movie night, learners calculate the average rate of change for two intervals. They compare the two and explain the relationship found in the comparison.

Context is the key to understanding slope. A real-world application of slope uses a weight loss scenario with a constant rate of change to introduce the concept of slope of a line, before it makes a connection to the ordered pairs and...

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...

Just how fast is the function changing? The presenter provides a general explanation of the average rate of change in the 28th presentation in a series of 31 calculus videos. The video moves on to find the average rate of change for a...

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...

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...

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 instructional activity even contains...

Step up to the challenge of finding the slope of stairs. Groups measure the rise and run of a set of stairs. They share their data with the rest of the class to determine a class average for the slope of the stairs.
