You will translate word problems (involving all four basic operations) into one-step equations.
After completing this tutorial, you will be able to complete the following:
Equations and Equality
An equation is a mathematical sentence that shows equality, includes an equal sign, and often includes a variable.
A relationship between mathematical expressions shows equality when the expressions are the same. For example:
5 + 8 = 13 x + 2 = 18
13 = 13 16 + 2 = 18
18 = 18
In order to solve real-world problems, you can write an equation to help you determine the answer.
Utilizing a Step-by-step Process When Translating Problems into One-step Equations
This Activity Object uses the following step-by-step process when translating problems into one-step equations:
1. Figure out what is being asked for, or identify the unknown.
2. Designate a variable to represent the unknown.
3. Select the words which show the relationship between the unknown and any other information given in the problem.
4. Determine the key word or words that indicate equality.
5. Determine the key word or words that indicate an operation.
6. Form the equation.
