You're trapped in a dark castle with a pile of gold coins that a wizard will only allow you to leave with if you can solve his riddle. Math learners solve the riddle of the dark coin with the help of an engaging instructional video.

There are three variables in the formula for a parallelogram. Two of the values are given in this problem. Find the third value. Identify what each of the variables means. Match up the given values to the variables. Then solve for the...

Use the formula for the area of a triangle to find the height of the triangle. If the problem gives the value of the area and the value of the base, then the height can be found using the formula for the area of a triangle. The...

Viewers learn how to calculate the volume when the cross section is not a circle by using the same principle as if it was a circle. The video goes through an example of finding the volume of a figure where the cross sections are squares...

There's got to be a better way. Scholars learn that the distributive property does work with subtraction and not just addition. Using that fact, the video shows how to find the product of two numbers by rewriting a complicated number as...

Talk about the unexpected! Young mathematicians, scientists, and artists will be enlightened by this short video that uses Van Gogh's Starry Night to depict the turbulent flow and the movement of light.

Dive deeper into subtraction. The presenter shows two more ways to use the definition of subtraction to solve subtraction problems. Using the distributive and commutative properties, pupils learn how to solve problems such as subtracting...

The definition of a kilogram is debatable. An informative video (as part of a larger playlist) shares the problem with the current definition of a kilogram. It explains why the concept became a challenge to explain as well as multiple...

Discover the power to simplify expressions. Viewers learn how to simplify expressions involving powers of exponents. The video covers five examples of this type of problem.

Build problem-solving skills within your classes. Young scholars learn linear equations are great for modeling contextual situations. The specific situation models weekly income based on a combination of salary and commission. Given the...

Scholars learn how to determine the area of compound shapes by finding the areas of the basic shapes that make it up. Pupils find the areas by adding areas together or subtracting them.

Practice using the product of powers rule to simplify an expression. Remember that only like-bases can be put together. Use the commutative property of multiplication to rearrange the terms and then use the formula to combine terms. Now...

Scholars learn how to approach a problem with multiple rules to apply through a video that demonstrates several examples with both integer and variable bases. They explore problems that combine two types of exponent properties.
