To take "the definitive portrait of that person in that moment" is the quest of photographer and hip-hop historian Jonathan Mannion. In this short video, Mannion details his dedication to his art and the process he goes through to catch...

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...

How will a scale factor affect a figure—negatively? Using a grid, the narrator of an engaging video performs a dilation with a negative scale factor. The presenter compares a positive scale factor with a negative scale factor to explain...

Turn the class around. Scholars define rotations of multiples of 90 degrees and create algebraic mappings for them. After an introduction to symmetry, pupils determine which letters of the alphabet have rotational and reflectional...

How did scientists measure the speed of incredibly fast things before the invention of high-speed photography? Scholars virtually perform ballistics tests to discover the process. They control the rifle type, bullet mass, and target...

Enlargements make it bigger, right? A video shows viewers how to perform a basic dilation with a fractional scale factor. They learn how to use the scale factor to find the location of the transformed vertex by multiplying the horizontal...

Breath life into the pages of a text with this instructional video on creating pop-up books. From choosing a topic, through the planning and creation phases, this video examines how to develop engaging visual...

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...

Can a horse pull more than its weight? A simple simulation answers this question and more. Pupils adjust the mass in a cart, the mass of the horse, the acceleration of the horse, and the angle of the tension rope between the horse and...

Does a yo-yo descend at the speed of gravity? The simulation explores angular speed and torque as a yo-yo is moved through a standard rotation. Scholars control the size and style of the yo-yo as well as the throwing speed. Challenge...

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...

How do you use a scale drawing to find the region in a lake where a treasure is located? The narrator of a short video problem identifies three criteria to determine the location of the treasure. Using a compass and ruler, he determines...

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.

It is all right to spend some time with a review. After watching a short review video covering the materials from the unit, pupils work through 23 review problems. Scholars work on problems involving the Pythagorean Theorem and its...

Solve problems around a circle. Pupils watch a video that shows how to apply concepts about circles and related angles and segments to find solutions to word problems. Learners then review the different concepts from the unit in...

Your learners will dance in their seats as this talented drummer connects math to music in a short video clip. Clayton Cameron shows how math puts the "cool" in various genres of music, including jazz, hip-hop, pop,...

Don't let your lesson plans go up in smoke—unless they include Boo Bubbles, of course! An engaging laboratory mixes liquid soap and dry ice to create smoky bubbles that burst on impact, making it the perfect way to celebrate Halloween in...
