Find the age of a fictional sample of rocks using a genuine approach. A well-designed lesson asks young mathematicians to use exponential modeling to analyze half-life. As a project-based learning activity, scholars communicate...

What an impressive task it is to make dental impressions! Pupils learn how dentists use proportional reasoning, unit conversions, and systems of equations to estimate the materials needed to make stone models of dental impressions....

Question: What do rectangles and bathtub volume have in common? Answer: Linear equations. Learn how to identify situations that have constant rates by examining two different situations, one proportional and one not proportional.

Students watch as the teacher demonstrates that y=ln(x) and y=e^x are inverse functions. They graph these equations on the same axes. Students work other log functions. They learn a Reggae Song about the log of the quotient. Students...

Ninth graders investigate the functional relationship of different environmental phenomena. In this math activity, 9th graders create models of various natural disasters. They use logarithmic and exponential functions to interpret...

Make the most of your prom—with math! Pupils write and use a quadratic model to determine the optimal price of prom tickets. After determining the costs associated with the event, learners use a graph to analyze the break even point(s).

It's the stairway to learning! Scholars research all aspects of building a staircase. Using information from building codes, they write and graph a system of inequalities to analyze the constraints. The completed project is a scale model...

Students pretend to borrow $1000.00 on a credit card. They pretend to make the minimum payments for a year. When they're done, they make a pie chart showing how much of their payments reduced their debt, and how much was interest.
