Two sides and an angle ... a triangle it makes. Given the measure to two sides and the angle between them, the narrator of a short video shows how to draw a triangle with a ruler and protractor. Pupils use handouts to practice the newly...

Creating a triangles is as easy as 5, 6, 7. Using a ruler and compass to measure off lengths, a short video shows how to construct a triangle with three specific side lengths. The example creates a triangle with side lengths of 5 cm, 6...

Two powerful video clips launch a study of race relations in the United States after the Selma, Alabama riots, the passage of the Votings Rights Act, and the riots in Watts, California. 

A four-part lesson plan features a video that details the life of a Mongolian queen. An eight-question quiz, related resources, and discussion questions follow the video to enhance the learning experience.

The narrator of a short video explains the steps in constructing a triangle given the measure of two angles and the length of the side between the angles. The resource provides opportunities for pupils to practice the skill with two...

Here is an activity that blends genetic technology, literacy skills, and critical thinking. Pupils review background information about cell lines and CRISPR by video and teacher-led discussion. Scholars collaborate to analyze two...

After a short review of the material from the Similar Figures Unit, pupils work through 18 problems to further practice the skills from the unit. Scholars apply those skills in the application problems at the end of the review.

Set the stage for a study of The Diary of a Young Girl with a resource that includes background information about Anne Frank's early years, the Nazi invasion of the Netherlands, her Secret Annex hiding place, and her capture and...

Critically apply intervals of increasing and decreasing. Pupils watch a video to see how finding a critical point and finding intervals of increasing and decreasing work together to identify local extrema. Scholars use the first...

The values keep getting smaller—quickly! Pupils watch a video that contrasts exponential decay with exponential growth from the first lesson in the unit. Learners identify exponential functions that are decaying and create graphs of...

Help! The leading coefficient is not one. Learners view a video showing a technique to factor trinomials when the leading coefficient is not one. Pupils try a few examples including solving equations by factoring and check their answers...

There might be an extra solution. Pupils discover that the process of solving a radical equation is the same general process of solving any equation. They find out that in some instances, an extraneous solution occurs. Individuals then...

Curious scholars make like Curious George and use their five senses to identify mystery objects. After a brief discussion, learners watch an engaging Curious George video in preparation for an activity. Scholars visit three tables that...

If you weren't already blown away by first two installments, check out this clip on how gravity and space-time interact! Our physicist friends, Pontzen and Whyntie, continue their discussion of these motion concepts for your high...

Some words are best left unspoken.  Words matter, according to Benjamin Zander, conductor, teacher, and lecturer. To illustrate his point, Zander recounts a story told to him by a survivor of Auschwitz. As a result of her experience...

Introduce learners to The Silk Road, the first world-wide web. The narrator of this short, animated video traces the pioneers of globalization and the impact they had on culture and economy. The Scythians, Darius the First, and Alexander...

Do all languages have a common ancestor? Although no one yet knows the answer to that big question, the narrator of this short, animated video explains how linguists use migration patterns, geological features, and word clues to...

Figure out what to do when there is no grid to count. Using a ruler and a sharp pencil, the narrator shows how to perform a dilation when the figure is not on a grid. The ray method works by drawing a ray from the center of dilation...

Where can it go? The first video on loci develops a definition and provides some quick sketches of the loci of all points with given characteristics. The presenter does an example of the loci of points a given distance from an L shape.

Got milk? Only two cultures have had it long enough to develop the tolerance of lactose as an adult. Learn how the responsible genes evolved along with the cultures that have been consuming milk. This rich film is supplied with a few...

Pupils learn how to find the derivative of a function by applying the definition using limits. Learners understand that the derivative provides the slope of the tangent line and use that information to find the equation of the tangent...

There has to be a quicker way. Pupils learn the power rule that allows for a shortcut to take the derivative of terms to a power. Using the newly found rule, scholars find the slope of the tangent line to a function at a given x value....

Time to take a second look at derivatives finding concavity. While watching the video, learners find out the definition of concavity. Individuals see how to determine whether an interval is concave up or concave down using graphs and the...

Are your students wild about horses? Then introduce them Sandra Olsen, a  zooarchaeologist, who has been studying horses and the people who herd them. Ms Olsen responds to 15 interview questions and details how she goes about her...
