Slope and Rate of Change Teacher Resources

Building on knowledge from the previous lesson, the second lesson in this unit teaches scholars to identify and interpret rate of change and initial value of a linear function in context. They investigate how slope expresses the...

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...

Discover an important property of linear functions. Learners use the slope formula to calculate the rates of change of linear functions. They find that linear functions have constant rates of change and use this property to determine if...

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...

The class will slide right into a clearer understanding of linear equations in this set of activities. By presenting slope in a variety of contexts, the emphasis rests clearly on the relationships that lead to the number. Learners turn...

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...

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...

New ReviewAn 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...

Learners will speed through this engaging unit on graphing rates and finding average rates of change with ease, especially given the wealth of resources provided. A variety of support activities range from student group problem-solving...

Explore slope using geometric patterns. Young mathematicians investigate towers built from cubes to develop a linear pattern. They move the data to a coordinate plane to connect the pattern to slopes.

Learners consider the rate of filling a cone in the 23rd installment of this lesson plan series. They analyze the volume of the cone at various heights and discover the rate of filling is not constant. The lesson plan ends with a...

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...

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...

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...

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.

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...

This lesson introduces the idea of slope and defines it as a numerical measurement of the steepness of a line. Pupils then use the definition to compare lines, find positive and negative slopes, and notice their definition holds for...

Pupils determine the pattern in collinear points in order to determine the next point in a sequence. Using the definition of slope, they practice using the slope formula, and finish the activity with three different ways to determine the...

Inquiry-based learning and investigations form the basis of a deep understanding of quadratic functions in a very thorough unit plan.  Learners develop recursive and closed methods for representing real-life situations, then apply these...

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...
