Just how much is 300 billion? There are supposedly this many stars in our skies! Mr. Vanden Heuvel calculates about how many blades of grass are in his lawn, but doesn't get close. Then he computes how many grains of sand there are in a...

Your statisticians will rise to the probability challenge while watching this video. A toy elephant is placed into one of 24 drawers. What is the probability of correctly guessing which one? As more drawers are opened, does the...

Do not pass this resource by! Everything you need to teach the property of density,and the separation of mixtures is here: an educational video, several classroom handouts, and a laboratory exercise. The video is engaging, though a...

An excellent lesson that encourages students to discover how complex figures can be broken into simpler shapes when measuring area. Working with block letters, learners are given the freedom to develop their own strategies for...

Let's heat things up! This simple experiment demonstrates for students the important role the sun plays in providing the earth with energy. Place one cup of water in direct sunlight and one in shade, then take measurements in order to...

Providing an exploration of parallel lines, this resource requires students to not only practice calculations, but also to analyze angles. By asking viewers to decide whether two lines are parallel based upon the information given, this...

Guava is on sale in this video. Here, two examples are shown to calculate a discounted rate.

As the fourth part of a series on the Pythagorean Theorem, Sal continues an exploration of the ways to calculate the length of sides of a right triangle using algebra. He also used this theorem to solve problems involving a right...

This lecture, the second in a series on the Pythagorean Theorem, delves into more complex problems. It primarily examines the process of finding the value of a hypotenuse. The example problem is beneficial because the solution is not...

Starting with a set of values for the x and y variables, this video shows how to tell whether these points determine a linear or non-linear function. Sal first defines linear functions in terms of the change in y over the change in x,...
