Wonder how many pieces of candy a teacher can eat. Pupils watch a video of candy in a bowl as some candy is removed to be eaten and others are added. Learners devise questions about the situation along with estimated solutions. Scholars...

Class members blend their knowledge of functions and problem-solving skills to provide business advice to the Turbo Blender manufacturers. Through a project-based approach, learners examine marginal cost data to produce a function....

In this Drake Equation worksheet, students read about how scientists can estimate the number of intelligent civilizations that may exist in our galaxy. Students answer 7 questions about the Drake Equation and they use the internet to...

Give AP Calculus classes the opportunity to check the accuracy of their calculations! A calculus activity involves the collection of data, the application of mathematics, and the analysis of the accuracy of results. Young mathematicians...

Explain the timing of a lake cleanup to the EPA using calculus. A project-based learning opportunity has learners compare rate functions to compute a total change. Their solutions explain the time needed to rid a lake of pollutants.

Common Core is all about getting your learners to open their minds and think about the why and how. This problem has them thinking about unknown numbers and their relationship with one another when we round and...

Using a real-world example, this problem illustrates the thought process that learners need to engage in to understand adding mixed numbers with common denominators. First by looking at estimation, and then by drawing models that...

Students connect literature (story Jelly Beans for Sale by Bruce McMillan) to math concepts. In these estimating and money lessons, students work with jelly beans, unifix cubes, pennies, nickels, dimes, and quarters, to estimate and make...

In this Computer Algebra System (CAS) activity students use Riemann sums to estimate the distance traveled on a trip at various speeds. They utilize the concept of Riemann sums to calculate the area under a curve. Students find limits of...
