Sometimes the easiest way to understand division is to look at it as multiplication. Show your mathematicians that every problem can be written backward to make it easier for them. The video explains how the relationship between...

Zoe is decorating a cake for her grandpa's birthday and needs to know how many more candles to add. Follow along as she explains how to set up and solve algebraic equations in this step-by-step presentation. Equations with negative...

Reinforce properties while solving equations. Learners often ignore properties even as they try to apply them. A well-designed lesson emphasizes the role of additive inverses when solving equations.

Understanding the inverse relationship between addition and subtraction is essential for developing fluency in young mathematicians. Zoe and RJ explain how three numbers can form fact families that make two addition and two subtraction...

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...

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...

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.

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...

Solve a matrix in code—color code. Pupils use the interactive resource to set up the matrix equation and its solution path. Scholars use the created solution path to determine the entries of the 2 X 2 solution.

In this electric circuit worksheet, students answer a series of 16 questions about logarithms and how they are used in understanding analog circuits. This worksheet is printable and the answers are viewed on-line.

Explore addition and subtraction and how they are related.

This activity helps with understanding how to balance an algebraic equation. You input the term and the operation. The activity uses that term, operates on both sides of the equation, then displays the resulting equation.

Use this web-based matrix calculator to solve for functions and operations.

Use the inverse operation to determine the original amount.
