Variables may be unknown, but expressions and equations are easy to understand. Pupils learn how to write, evaluate, and simplify numeric and algebraic expressions. They also investigate how to write and solve simple equations and...

Find the right balance between concrete and abstract thinking. After using interactive balances to explore inverse operations, learners solve multi-step equations with variables on both sides. Of course, they can still use the...

It's not a time machine—it's a function machine! Using two rules, the video introduces a function machine that changes an input to an output. Pupils answer questions such as finding what is the input for a given output and what values...

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.

Here's the solution to your equation-solving needs. An informative YouTube video discusses how to determine whether a value is a solution to a one-step equation. It then goes on to solve these types of equations using addition or...

Multiply your efforts in solving equations. Viewers of an instructive YouTube video learn how to solve one-step linear equations. Examples involve multiplication or division, with some equations having fractional coefficients—great...

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...

As if solving multi-step equations isn't challenging enough, now they have decimals! The video lesson explains strategies for working with these decimals while solving. Learners watch as the video instructor explains how to solve two...

Time to distribute some learning! The video lesson teaches how to solve an equation by applying the distributive property. Learners watch as the instructor completes each step, explaining as he goes. The first step to solving uses the...

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...

Not only can equations have many steps to solve, but those steps can look very different from equation to equation. The narrator of the video lesson explains the steps to solving six different multi-step equations. He provides...

Reverse the wrapping to get to the gift. Using the idea of unwrapping a gift, the lesson introduces the concept of inverses. Pupils first determine the order needed to evaluate a function at a point, then use the reverse to find the...

Don't lose your marbles as your learn about addition and subtraction equations. Pupils investigate the relationship between addition and subtraction by using an interactive. They drag different color marbles into a box and identify the...

Solving equations is a piece of cake. Young mathematicians use an interactive to create a bar model to representing a situation involving cupcakes. They use the model to solve for the cost of a cupcake.

The rules still hold. By reviewing the meaning of exponents in arithmetic, the video takes a look at exponents in algebra. The resource develops the meaning of any number raised to the zero power. Taking the idea of exponents further,...

Bring balance to your lesson plans with an activity that asks individuals to solve one-step linear equations with inverse operations. Balance scales help learners understand the concept of isolating the variable.

What makes number pairs perfect? The resource provides five problems regarding perfect pairs of numbers, the definition of which changes in complexity with each task. Solutions require pupils to apply number sense and operations, as well...

It's time for them to show you what they've learned! The review provides a sampling of the different concepts learned throughout the eight-part series. Learners solve equations by combining like terms, applying the distributive property,...

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...

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. 

What does order of operations have to do with solving equations? A video explains solving two-step equations using a do/undo chart. Learners recognize the operations within an equation and use inverse operations to undo those operations. 

Where did all the variables go? Scholars learn how to interpret an equation when they eliminate all variables during the solving process. They interpret the solution as infinite solutions or no solutions. 

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. 

Reinforce math vocabulary with a set of flash cards. Forty-eight cards offer boldly printed words, and their corresponding definition alongside an example with labels. Terms include absolute value, inverse operations, slope, and more!
