Here's a creative lesson that lets pupils be creative as well! While considering many different factors, learners devise a plan to increase the efficiency of container shipments. The design of the activity encourages creative,...

High school is the time that many scholars get their first jobs. Help young entrepreneurs apply economic principles to crucial skills for their new jobs and for functioning in society in general. They use Excel to balance a checkbook by...

Take a chance with an activity sure to improve your class's skills. An introductory activity focuses on probability and chance. It shows how probability is always a value between zero and one, i.e., the probability of an event is always...

Don't let your class's heart rates rise as you introduce them to differentiation ... an inquiry-based lesson helps them keep it in check! The second lesson in a three-part series asks learners to analyze the rate of change of different...

Some of us never feel like we know how to do our taxes! Help scholars understand the process early by using an informative resource. They fill out their own tax forms in a simulation activity and view multiple resources to learn even...

Rise to the challenge of trigonometry. Watching a video of an ascending funicular at the Sacre Coeur in Paris sets the stage for a challenging task. Young mathematicians use a given diagram, along with the concepts of slope and...

Lay out a firm understanding of trigonometry. Scholars watch a video recording of a worker laying sod on a lawn. Given the dimensions of each piece of sod and the lawn, they determine how many pieces of sod are necessary. Trigonometry...

Who's on second? Young mathematicians use a diagram of a baseball field to find the distance a catcher must throw to reach second base. A brief video of such a play during a baseball game sets the stage for the assignment.

Come look at trigonometry from a different angle. To begin a simple activity, scholars view a video of someone using a clinometer to find the angle of elevation to the top of a building. They then use a diagram that shows the building's...

The task will fit your needs to a tee. Given pictures and dimensions of a golf green, future golfers determine the distance it would take for a golf ball to land on the green. Of course, we want some mathematical connections, so they...

Which is the best reflection of them all? Given four diagrams, pupils determine which one shows the most accurate reflection of a quadrilateral. Two images provide the distances of each vertex from the line of reflection, as well as the...

Of course, there might be a correlation! Young mathematicians investigate several different data sets, create scatter plots, and determine any correlation. They consider whether a causation exists between any of the variables in question.

Flip a coin: heads, use the resource; tails, use the resource. The fourth of six installments of the Statistics & Probability unit looks at coin tosses and probability. The class conducts an experiment and sees that the outcomes of...

Life's not fair, but dice games should be. After playing a two-person game with a pair of dice, scholars investigate the fairness of the game. They consider the number of possible outcomes using the fundamental counting principle and...

It's all relatively simple once you get the gist. Young mathematicians learn about sample spaces and simple probability by conducting an activity with dice. To complete the second of six parts in the Statistics and Probability unit, they...

From derivatives to antiderivatives and back again. Building on the second lesson of the three-part series covering functions, learners explore the concept of an antiderivative. They connect the concept to the graph of the function and...

First there was pi and now there's e. A discovery-based lesson helps learners find a pattern in compound interest as the compounding period changes. Their investigation results in the discovery of the number e. The lesson is the first in...

A penny saved is a penny earned! Scholars research the different ways to save money over a lifetime. They investigate the Rule of 72, compound interest, and sub-prime loans to gain an understanding of how banks aid in the saving process....

Have you ever checked your clothes to see how many nations created them? Pupils take a deeper look at international trade and the balance of payments nations have with one another. They use calculations, simulations, and primary sources...
