How can you safely model exponential growth and decay? A hands-on activity uses candies to model not only exponential decay, but also exponential growth. Exponential equations are fitted by hand and by use of a calculator to the data...

How do you make a penny grow to $5,000 in just 15 days? Use the examples in this lesson to explore the concept of exponential growth and its comparison to linear models. Pupils come to understand that exponential growth eventually...

High schoolers graph exponential equations and solve application problems using exponential functions. They re-enact a story about a peasant worker whose payment for services is rice grains doubled on a checker board. They place M &...

Graph that function! Learners explore how the shape of a graph relates to the function the graph describes. The instructional activity uses teamwork and Function Journals to reinforce new mathematical vocabulary.

Keep your mathematicians engaged using this group linear functions activity. Each of ten groups receives two graphs with both an image and equation, as well as a "who has" phrase to call out the next graph. Scholars stay on their toes as...

Expand your knowledge on exponential growth! A concept video features the definition of an exponential function. Eight problem videos cover graphing exponential functions, identifying exponential growth and decay, and applying...

Show your class how to use properties to make graphing easier with a resource that explores the graphs of quadratics. Using tables to determine the points to graph, pupils discover the symmetry of parabolas in order to short cut the...

Sketch graphs with the Graph Sketcher. Scholars graph functions on a coordinate plane. An interactive makes it as easy as inputting the function and clicking a button.

We have calculators, so why do we have to do this by hand? The video takes viewers through graphing scientific data by hand to create a scatter plot. The process includes labeling axes, writing an appropriate title, determining a scale,...

Help learners recognize the characteristics of a quadratic graph and how changes affect them. An informative video uses a graphing calculator in order to find out what happens when the leading coefficient of a quadratic changes. The...
