Patrick Jmt: Permutations: Counting Using Permutations

Counting is not all it adds up to be — sometimes it involves multiplying. The lesson introduces permutations and combinations as ways of counting, depending upon whether order is important. Pupils learn about factorials and the formulas...

This video is an introduction to permutations. Sal shows two examples, defines the mathematical notation for permutations, and derives a formula for finding a permutation without repetition of choices. He tries to convey an intuitive...

The notion of permutations is used when rearranging objects or values. How many ways can the letters in the word NUMBER be rearranged? Don't try writing them all out one by one because it would take a long time. Use the Fundamental...

Sometimes all you need is an image to help solve a word problem. This tutorial shows how drawing picture can help you determine a correct number of possibilities with given data. You can also use the FCP or fundamental counting principle...

Video tutorial provides examples and tips for comparing two fractional expressions using inequalities. [1:46]

What's in a name? An interactive asks users to find the number of ways to arrange the letters in the word DAD and MOM. Pupils use the interactive to arrange the letters but restrict the permutations to be unique for MOM and answer...

Here's a sweet resource on sample spaces. An enticing interactive allows users to list all possibilities for the flavors of candy given to a friend. Scholars must also determine whether permutations or combinations are more...

Learning math from an ice cream shop—what a tasty treat! Individuals use an interactive to list all possibilities for a double-scoop ice cream. Along the way, they learn to distinguish between permutations and computations.

Oh my, five types of bread, eight kinds of lunchmeat, and six choices of cheeses. How many different combinations of sandwiches can be made? That's going to take a long time to figure out. No, it's not. Just use the Fundamental Counting...
