Solving One Step Equations: Addition and Subtraction

Mrs. Zimmerman teaches sixth graders how to solve one-step equations using addition and subtraction. The lesson covers checking if a value is a solution, using inverse operations, and solving equations with decimals and fractions. Students also learn to apply these skills to real-world story problems.

• Yes, because 18 + 10 equals 38

• No, because 18 + 10 equals 28

• Yes, because 18 + 10 equals 28
