Rate-of-Work Problems

The concept of slope gets an approachable, yet theoretical, treatment in a comprehensive algebra lesson. The use of functional notation and problem-solving techniques keep the material rigorous, but detailed teaching notes and lots of...

Learners investigate average rates of change for linear functions and connect the concept to slope. They then determine average rates of change in quadratic and exponential functions.

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...

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...

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...

Let knowledge of rates of change flow into a lesson. By watching a video, pupils see an additional real-world example on rates of change. Using provided information about a leaking water tank, they complete a table of values and plot a...

Word problems are full of valuable information that can be used to create equations. Take your learners on an adventure and figure out a formula that will represent the cost of a rental car. The video asks questions to help understand...

Here's a great lesson that looks at slope as an instantaneous change. Using an estimated tangent line, the presenter shows the class how to find an approximation for the instantaneous rate of change. Scholars determine the slope of the...

Simply find the slope to find the average rate of change. A short video provides the definition of the average rate of change. Using the definition, pupils calculate the average rate of change to solve problems that cover finding average...

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...
