Introduction to Permutations and Combinations

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...

Now that we know about permutations and combinations, we can finally solve probability problems. The fourth installment of a 21-part module has future mathematicians analyzing word problems to determine whether permutations or...

Need to prep your science learners in math? Here is a resource that serves as a review guide to support your scientists with the math they need to be successful in chemistry. Comes with basic algebraic problems and a review of...

Count the benefits of using the resource. The second installment of a 21-part module focuses on the fundamental counting principle to determine the number of outcomes in a sample space. It formalizes concepts of permutations and...

Do your pupils confuse multiplying variables terms with adding variable terms? A video presentation uses factoring to isolate the coefficients of the like terms before combining, emphasizing the difference between addition and...

Combine a video into your lesson plans. Young mathematicians view the informational video to learn about combining like terms. They watch as the narrator works through four examples of combining like terms by applying the distributive...

How does the Fundamental Theorem of Algebra apply to equations with complex roots? Using recently learned concepts about the complex plane, learners determine all the complex roots of polynomials. They can find the same roots...

The author of this video makes use of digital tools to show substitution into the permutation and combination formula. The differences between the meaning of permutations and combinations is also discussed.

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...

Entertain and grab your learners' attention with a short video clip that engagingly teaches the concept of a permutation and how a factorial is a wonderful shortcut for theoretical probability calculations.
