ONE STEP EQUATIONS

Equations are balanced on the equals sign, so what is done to one side of the equation must also be done to the other side of the equation. First, we’ll look at solving addition and subtraction equations by using cups and chips.

Equations can be solved mathematically by performing the same computations to both sides of the equation to “isolate” the unknown on one side of the equation. We will look at the steps that can be used to solve addition and subtraction equations mathematically using paper and pencil.

Next, we will explore solving multiplication and division equations by using cups and chips. Remember, equations are balanced on the equals sign, so what is done to one side of the equation must also be done to the other side of the equation.

Equations can be solved mathematically by performing the same computations to both sides of the equations to “isolate” the unknown on one side of the equation. We will apply this rule to solve multiplication and division equations mathematically using paper and pencil.
