It's important to have the correct number of flower arrangements at a wedding. Scholars match an inequality and a graph given a situation involving roses for wedding receptions. A set of challenge questions checks the matching pairs.

Ride to success in checking solutions to equations. Scholars use an interactive graph to identify points that are solutions to a linear equation. Interpreting these points in terms of the context completes the activity.

How does inertia affect an object's trajectory? After watching a video on safety belt use, pupils discuss the notions of inertia. Using their knowledge, individuals try to drop a ball on a target while running, and classmates observe the...

Make money disappear! Young scholars watch as a copier shrinks a dollar bill to 75 percent of its size. Learners are left to determine the size of the dollar bill after nine passes through the copier.

The shortest distance from point A to point B is a straight line—or is it? Young scholars determine the shortest route either along a circular path or through the center of the circle. Learners gain a unique perspective on arc length and...

Investigate the volume of irregular figures in an inquiry-based exercise. Presented with an irregularly shaped box filled with water, learners must predict the level of water when it is tipped on its side. The class can divide...

Analyze patterns in a circular arrangement. After using a geometric construction to complete a circle, learners use proportional reasoning to make predictions. By determining the length of an arc built from suitcases, they estimate the...

Sometimes losing is actually winning! Learners use a proportional analysis to compare percent weight loss of contestants on The Biggest Loser. The resource provides data and clips from the show to facilitate the lesson.

Don't let the learning in your classroom get jammed up! Intrigue your scholars with an open-ended scenario to explore. A video presentation shows a challenging stretch of road that is susceptible to traffic jams. The task is to determine...

For every action, there is an equal and opposite reaction. In the case of the blob, that reaction is a trip several feet in the air! Learners begin by watching the world-record blob jump. They then analyze the flight of the person using...

Have you ever wanted to download a great lesson, but you weren't sure if you had enough time? Scholars learn to create a function for this situation to determine when a file will finish downloading. They also learn the difference between...

Understanding volume means less mess in the kitchen. Viewers observe a can of peas and a small bowl. They must determine if all of the peas from the can fit into the bowl without spilling using volume formulas to solve the equation.

If money was left in an interest-earning account for 1,000 years, how much would it increase? Viewers watch a clip from a show about the future when someone learns about their balance after 1,000 years. Then, they solve for the amount in...

Unscramble a carnival mystery! Scholars observe a video of an overhead view of a carnival ride, The Scrambler. They then must determine mathematically where a specific car will stop after a certain amount of time.

As the saying goes, a penny saved is a penny earned. Young scholars use a penny activity to earn their way to an understanding of volume. Given three different-sized cylindrical containers, individuals make calculations to determine the...

What would a meal be without the taters? The question is, how long does it take to peel those potatoes? Given the rate of peeling one potato, scholars predict the time it takes to peel the bag. The twist is that the first potato was...

Does your coffee get too cold too fast? Joulies just might be your answer! Learners use experimental data to make a conclusion about how effective Joulies are at keeping coffee at the ideal temperature. A video shows the graph of the...

Package design is a mathematical task for any business. Young scholars use a package design to determine the number of packages required for specific shipments. Using ratios, proportions, and fractions, they make decisions about the best...

Teens might find it hard to imagine life before GPS. Using global positioning systems, they can quickly locate the nearest gas station, fast food establishment, or the home of a new friend. Introduce them to Gladys West, the lady who...

Build up a bag of green. Pupils determine the number of green Skittles in a snack bag and come up with a way to determine how many snack bags it would take to create one bag of only green Skittles. Classmates share their methods and...

Mix up your teaching playlist with a performance-based assessment task. Given iPod sales data for several years, scholars create a scatter plot and perform regression analysis. They determine the best fit curve for different domains.

Given the price of crude oil, gasoline, and diesel for the past several years, pupils plot the data to determine whether a correlation exists. Learners determine a regression line and predict the price of gasoline and diesel in the...

Move beyond setting up equations. Pupils continue with optimization problems and use their knowledge of derivatives to find solutions. They watch as the video uses equations from previous examples and find solutions to answer specific...

Let's get the equation set. Pupils see the importance of setting up an one-variable equation in the first of two lessons on optimization problems. The presenter works four different types of problems before individuals use the included...
