Slopes and Rate-of-Change

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...

In this understanding slope activity, students solve 13 various problems that are related to determining the slope of a line. First, they calculate the rate of change by analyzing the differences in the x- and y-values. Then, students...

It's shark week! In this problem, young mathematically minded marine biologists need to study the fish population by analyzing data over time. The emphasis is on understanding the average rate of change of the population and drawing...

With this resource, high schoolers solve 17 types of problems related to the transformation of linear functions. First, they define parent function and determine how other linear functions compare to the parent function. Then, pupils...

An inquiry-based algebra lesson explores real-world applications of linear functions. Scholars investigate four different situations that can be modeled by linear functions, identifying the rate of change, as well as the strength and...

Submerge yourself in the study of slope. Scholars investigate a situation involving slope and the rate of change of a submarine. An additional example further explores the concept of slope by changing one of the conditions of the submarine.

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...

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...

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...

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...
