Scholars' knowledge of probability depends on whether they watch the useful video. Young mathematicians view a short video to learn about the probability of dependent events. The narrator works through several examples to ensure viewers...

Sample the resource and decide to use it all. Viewers of the informative YouTube video learn to use tables to represent sample spaces for compound events. They use these tables to help determine probabilities.

Use the resource or lament lost opportunities. Scholars watch a short video to learn about the probability of compound events. First, they see how to find probability of or events that are mutually exclusive. They then use the addition...

Simple probability can be quite simple. An instructive video describes how to determine probabilities by considering possible outcomes. It uses a variety of contexts as examples to cover the topic.

Toothpicks are as good a manipulative as any. Young mathematicians view a short video that introduces a toothpick puzzle. By moving one toothpick, they must produce a correct equation from an incorrect one.

Third example's the charm. To learn about simplifying expressions, young mathematicians watch a short video that shows how to simplify an algebraic expression using several properties of exponents.

If only everything could be simplified so easily. Viewers of an educational video learn how to apply properties of exponents to simplify expressions by using the product, quotient, and product rules for exponents.

Feel like you're going in circles? The fifteenth lesson in a series of 29 videos gives pupils a resource for writing equations of circles in standard form. Once in standard form, the instructor graphs the circle.

Demonstrate how to use a box and whisker plot to place a line of best fit accurately with an educational video. It begins with a review of box and whisker and line of best fit, and then uses an application problem to describe the...

Relationships can be good or bad, but functional relationships are the best! The video demonstrates relationships in a table or graph and what makes their qualities functional. Have your learners review functions and then go through a...

Acute, obtuse, right, and straight are all different types of angles. This clip provides a brief definition and example of each of the four types of angles. Tip: Have your class go on an angle hunt, the team that finds the most of each...

Brian explains about variables and uses cookies and friends to set up an example. He poses a word problem and then goes through the process to solve for the variable.

Find the height of a trapezoid given the values of the two bases and the area. First write out the formula for the area of a trapezoid. Then identify all the variables and match up the given values. Now plug the values into the formula....

Learn how to use the formula for area to solve a problem about a rectangle. The demonstrator shows how to plug in the known values of a rectangle, and then how to use the formula for area to solve for the variable in question.

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...

So you are trying to tell me that a parallelogram is a rectangle in disguise? Wow! And I can use a similar formula of the area of a rectangle to find the area of a parallelogram? Wow! Ok, show me how! A=bh. So simple really.

Trying to find the area of a rectangle, a triangle, a circle, or a parallelogram? There are specific formulas to use to calculate the area of these shapes. But the given shape is not any of these. It's a composite shape, which means it...

Slice a large piece of pie or slice a small piece of pie? Whichever way you slice it, this piece of pie would be a fraction of the whole pie. This analogy corresponds with the sector of a circle being a piece of the pie. The size of the...

There are actually two formulas to find the circumference of a circle. One formula is based on knowing the diameter of the circle, and the other is based on knowing the radius of the circle. The instructor illustrates both formulas. She...

There are two formulas that can be used to find the circumference of a circle. Choose the appropriate formula depending on the given value in the problem. After selecting the correct formula, solve the problem using 3.14 as an estimation...

Are you looking for the formula for the area of a sector of a circle? But what's a sector? A sector is just a fraction of the area of a circle. Follow the instructor as she illustrates and labels the different parts of a circle. She also...

There are basically two things you need to know to find the area of a circle. First, you need to use the correct formula. Second, you have to know the value of the radius. If you know these two things then all you have to do is plug the...

Do you know the formula to find the area of a circle? Do you know the value of pi? Do you know what the relationship is between diameter and radius? Yes? Then you can solve this problem. If your scholars don't know this formula then this...

Cut up a circle and make a parallelogram! What? No way! Yes way! Watch the instructor illustrate just how to cut up the circle and get that parallelogram to then get the formula for the area of a circle. It really works! Base,...
