Planning a unit on simple machines? Save some time and energy with this collection of lessons and activities that explores how these devices are used in the real world to make life a little easier. 

Solving equations in two variables can't be that much harder than solving equations in one variable. Using a balance interactive, scholars solve equations in two variables. They apply inverse operations by adding -x, -y, or -1 as...

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...

Not all interactives are made equal. Scholars use an interactive balance to explore the concept of equality. They place different objects on balances to determine the number of each object needed to balance the scale.

Keep track of your sixth graders' mastery of the Common Core math standards with this practice assessment. Taking a different approach than most standardized tests, this resource includes not only multiple choice questions, but also...

Join Zoe and Sam as they use proportions to budget money for their Green Earth Club. Watch as they set up and solve a series of proportions using cross multiplication and division. A great resource that brings together prior knowledge of...

Brainiacs explore the concept of solving single-variable equations.They use inverse operations to solve equations, and participate in activities such as balancing an equation scale. This is an awesome instructional activity, complete...

Find a quick, concise explanation of the properties of inequalities. Examples are given and clearly explained for each of the properties.

[Free Registration/Login may be required to access all resource tools.] In this lesson students learn how to solve real-world problems involving inequalities. Students watch a video tutorial, explore guided notes and attempt practice...

[Free Registration/Login may be required to access all resource tools.] On this site students learn to verify that solutions to inequalities are correct. Students can watch video tutorial, look at key vocabulary and attempt practice...

Students are given two equations and will use inequality symbols to compare them.
