Writing and Solving One-Step
Linear Equations In One Variable
- Make sure students know the three important ideas for solving linear equations: (1) get the variable onto one side by itself; (2) use the inverse operation to undo what was done to the variable; and (3) make sure the equation is kept in balance by doing the same thing to both sides of the equation.
- When solving word problems using equations, be sure students write down what the variable represents.
- Be sure students check their answers in the equation to see if the answer makes a true statement.
- Have students properly label their answers. Most answers will require a label if the answer is for a word problem.
- Constantly remind students that addition and subtraction are inverse operations and that multiplication and division are inverse operations.
- When solving word problems, be sure to emphasize the four-step process.
- Give students an equation like y 6 = 19 and ask them to write a word problem that could be solved by solving the equation. Reversing the process is a good way to help your students gain understanding of word problems.
