Slopes and Rate-of-Change

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...

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...

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...

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...

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...

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...

Mathematicians apply the formula for line slope to determine the slope of stairs in their school. They work in small groups to take the appropriate measurements, perform the necessary calculations, and find the mean of their group slope...

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 activity even contains extensions for more...
