Combinations and Permutations

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...

Put on your thinking caps because middle school math has never been more interesting in this huge resource full of thought provoking questions. Written as a newsletter, the resource has 10 two-page newsletters with a variety of...

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...

Odd or even—fifty-fifty chance? Pupils first conduct an experiment rolling a pair of dice to generate data in a probability lesson. It goes on to introduce mutually exclusive and non-mutually exclusive events, and how to use the Addition...

Here is an equation in which the first step is to use the distributive property to get rid of 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...

Your learners will be surprised by the thought-provoking, counterintuitive puzzle presented in this short video that models a fun, fictional situation in which a game is played with two number cubes to decide which of two people wins a...

How can an equation have infinitely many solutions? Viewers first review the basic idea of solving a linear equation by applying inverse operations in the concept video. Four problem videos cover examples in solving linear 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...

This lesson has a number of fun worksheets for a pre-algebra or beginning algebra class. The main emphasis of this lesson is functions, formulas, and looking at square roots. It is the third lesson in a series on solving for unknowns,...
