New ReviewThe house lights dim, the curtain parts, lights slowly come up, revealing the stage. Before the actors appear, before a word is spoken, the audience is drawn in by the lighting, by the colors, by lines of the set, by the props, and...

New ReviewTwo-d or not two-d? That's not really the question because the figures here are all two-dimensional. Learners identify the names of polygons, starting with triangles and ending with decagons. The video also describes circles and...

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

New ReviewDon'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...

New ReviewTake the edge off of learning about solids. A short video explains how to count the number of edges, faces, and vertices of three-dimensional figures. It works through several examples, including a cube, a square pyramid, a triangular...

New ReviewYou've netted a great resource! Young mathematicians learn about the nets of three-dimensional solids by watching a brief video. The resource includes some test-taking tips on the topic for those studying for the GCSE.

New ReviewWill this be on the final exam? A brief YouTube video shows scholars how to use the table feature of a graphing calculator to find the necessary score on a final exam to achieve a specific course grade. The example uses weighted averages...

New ReviewYour final exam is the final opportunity to shine. A short YouTube video teaches viewers how to determine what score individuals must receive on the final exam to get an A for the course. It shows how to set up an equation using weighted...

New ReviewSit back and watch pupils calculate their own grades. Through a short YouTube video, individuals see how to do the calculation by watching an example. They learn how to account for weighted averages in the computations.

New ReviewThe point is—use the video. A short YouTube video describes how to find the number of additional points individuals need to get an A in a class that uses a point system for grading. It also looks at what percentage these additional...

New ReviewRise 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...

New ReviewJump at the chance to use a crazy fun resource. After viewing a short movie clip of a motorcycle stunt, scholars determine whether the motorcyclist will clear a row of buses. They'll likely use a graph of a quadratic function to make...

New ReviewLay 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...

New ReviewLuckily, he hit the air bag. Scholars watch a video from the Guinness World Records that shows a stuntman falling from 342 feet. The task at hand is to determine his velocity when he hits the air bag. Thank goodness for the cushion!

New ReviewCoffee drinkers, rejoice, here's a chance to win free coffee! Coffee club card holders have the chance to win free coffee every day for a year—but they must enter using their cards good for a free cup. Scholars weigh the chances of...

New ReviewRun headlong into a great resource. Young mathematicians explore the Nike+ app to see which measure of central tendency motivates runners the most. They use two screenshots of the app to help them make their determinations.

New ReviewIt's extremely important to pace yourself. Scholars watch portions of a video of the 2014 Nathan's Hot Dog Eating Contest. Using pictures that show one contestant's number of hot dogs at various times, they use rates to estimate how many...

New ReviewMoving a house is hard work. Given a diagram of a row of houses, scholars determine a set of transformations that would map one house to the next. A second diagram with a coordinate plane helps with the task.

New ReviewWho'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.

New ReviewCome 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...

New ReviewThe 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...

New ReviewWhich 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...

New ReviewOf 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.

New ReviewFlip 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...
