Combination and Permutations

This two page learning exercise contains 32 problems to solve. There are examples given for each set of problems. The first set is to work on adding or subtracting a term to get the variable by itself. The second set is about dividing...

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 there are parentheses in these equations? As the lessons continue in this series, equations get progressively more complex. Eighth graders solve equations by applying the distributive property before using inverse operations. 

Where did all these variables come from, anyway? The previous lessons in the series ask learners to solve multi-step equations using the distributive property, combining like terms, and using inverse operations. Now scholars solve...

Many learners find completing the square the preferred approach to solving quadratic equations. Class members combine their skills of using square roots to solve quadratics and completing the square. The resource incorporates a...

How do you make these x's get along? Building on the previous lesson in the series, learners solve equations by combining like terms. The video uses objects to help pupils understand the concept. 

Teach solving equations on your terms ... like terms, that is! Multi-step equations take many forms and require a series of different steps. A video lesson shows the steps of solving an equation that requires combining like terms. After...

Inverse operations are the key! A video instructor demonstrates solving multi-step equations involving the distributive property and variables on both sides. The lesson includes step-by-step instructions for three different equations.

You know how to find absolute values and you know how to solve inequalities — but what happens when these two concepts are in the same problem? A YouTube video first reviews absolute values and moves on to solving absolute value...

Solving equations is the groundwork for all of algebra. A video presentation explains the steps for solving an equation with variables on both sides. Using a different color for each step, the instructor shows how to manipulate the...
