The name of this app may sound a little gross, but there's nothing gross about learning math with game-based practice. Rich and Jennifer demonstrate just how to line up your crackers in order to avoid the goo, and learn some...

Foldables in an app? Cool! You can learn all about it in this video. Jennifer and Rich show you what the app is about by walking you through how to create and print custom foldable materials.

Are you trying to integrate technology into the elementary math curriculum but having trouble finding the right tools? Rich and Jennifer are here to help as they explore this fun skills practice app and point out considerations when...

Kids love animals, so encourage them to explore matches with animal-themed math. Jennifer and Rich present the app's features, spending particular time on how to use it and apply it to your classroom needs.

Well, the long and short of it is that this is an excellent app for practicing long division! Rich and Jennifer demonstrate how to use the program and walk through additional features offered by the app.

Pupils watch a video to learn about different types of sample design and how to use technology to create a random sample. They discover different types of bias that may happen due to the sampling design or the questions. Learners use...

This video focuses on rational expressions and completes Sal's lecture series on working with and solving this particular type of equation. Its length would be ideal for a computer lab visit or homework assignment (in conjunction with a...

Useful as a classroom resource, a computer lab assignment, or even a homework supplement, this video shows viewers some more techniques for factoring polynomials. Once they have mastered the art of factoring, the rest of algebra will...

One of the strongest tools an algebra learner develops is the ability to quickly and accurately graph almost any given function. Often doing this quickly and accurately requires rigid transformations to a parent function,...

This comprehensive introduction to rigid transformation of functions does a fabulous job of breaking down translations and reflections into manageable concept chunks. Care is taken with horizontal translations, vertical translations,...

Trapezoids can be tricky! Break down the process of finding the area of a trapezoid with an engaging math video. Learners explore area formula and shown exactly how to plug in information, solve, and simplify. 

Adding double-digit numbers can seem difficult for some students. But this Khan Academy video makes this process clear in a developmentally sound way. Students watch as 'Sal' adds the number 46 to 43. He references each number by its...

Viewing this Khan Academy video helps with grasping the concept of place value. Learners write the word six hundred forty-five million, five hundred eight-four thousand, four hundred sixty-two in standard form, using multiplication as a...

There are particular ways to multiply binomials. One could use the FOIL method or employ the distributive property. Sal walks through each step of the FOIL method and then shows that using distribution results in the same answer. This is...

This is the second in a series of three Khan Academy videos on rounding whole numbers. Students watch Sal Khan round the number 423,275 to the nearest thousand by looking at the number in the hundreds place. If it is five or higher, you...

Show your students this presentation to help them understand how to add fractions with like denominators. Sal adds 3/15 to 7/15 and then simplifies his answer. He uses drawings and multiple colors to show the actual process.

Before Sal can divide a mixed number, he has to rewrite it as an improper fraction. He explains that dividing a fraction is the same as multiplying it by its reciprocal and that you can "cancel out" numbers to make multiplying easier.

Divide two polynomial expressions by writing the problem as a fraction or as long division. Sal shows how to use long division to divide polynomials. A solid understanding of polynomial operations is necessary to grasp this video.

Sal Khan completes the three-part rounding series with this Khan Academy video on rounding to the nearest 10. He references the actions taken in video two, so students would be best served if all three videos were shown in sequence.

Rounding is an essential skill that must be used throughout the study of mathematics. This Khan Academy video is the first in a series of three. It shows how to round the number 24,259 to the nearest hundred, using a number line.

Adding two polynomials begins with simplifying when possible. Sal demonstrates the process he uses to combine like terms and explains why the process works. This video would be great for those who need a quick refresher.

Let's think about how a person could simplify an expression where a polynomial is divided by a monomial. Sal shares three different modes he could use to simplify, then uses each way to solve the same problem.

Here is a quick look at how one could simplify a monomial expression involving division. Sal works on a problem and briefly explains his process. Great as a concept review.

Apply the concept of scientific notation to a word problem involving the rate of speed. Sal explains how to express the answer using scientific notation.
