Permutations & Combinations

This two page worksheet 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 both sides...

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...

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...

Challenge your mathematicians to simplify and solve a variety of different equations. This worksheet focuses on multi-step problems that begin with combining like terms and advance toward solving equations with variables on both sides. A...

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...

Here is an equation in which the first step is to use the distributive property to remove the parenthesis. Then, it is solved for the variables. Since there are variables on both sides of the equation, it is important to verify the...

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.

Combine like terms before solving the equation. This should be a rule of thumb. The goal is to isolate the variable, so it stands to reason that if you have more than one of the same variable, you would combine them. See how the teacher...
