Determining Rates from Graphs

If only there was a graph to show the distance traveled over a period of time. Given distance-time graphs, pupils read them to determine the answers to questions. Using the distance and time on a straight line, scholars calculate the...

At this rate, you'll know all about ratios in no time. Scholars view a short video that discusses advanced concepts regarding ratios and rates. They first determine the speed of a subway from a graph, and then find unit rates given...

With his trusty graphing calculator, Sal begins his lecture on solving quadratic functions by graphing. The video is a good way to show young mathematicians not only how to use the graphing calculator (which Sal describes as "archaic"...

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...

Slopes are not just for skiing. Instructors introduce class members to the concept of slope and teach them how to calculate the slope from a graph or from points. The lesson also includes the discussion of slopes of parallel and...

A Cyberchase video introduces the distance = rate x time equation. Participants then calculate answers to proposed problems and graph a series of results that is then incorporated into a game to help cement the concept. A thorough and...

Explain how to find the slope of a graph of a line with a video that points out how no matter what two points are used on a graph of a line, the slope is the same. A few examples reiterate how to find the slope of vertical...

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...

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...
