Integer Operations — Integers worksheet for Grade 6.

Negative integers model many real-world situations 6th graders encounter or will encounter soon. Temperature below zero, owing money (debt), elevations below sea level, and game scores where you lose points all use negative integers. Understanding them now builds foundation skills for algebra, science, and financial literacy in later grades.
The negative sign in front of a number tells you the number's value (e.g., -5 is 'negative five'). The subtraction sign is an operation that tells you to take away or remove. For example, in '3 - 5,' the dash is subtraction, but in '3 + (-5),' the dash is a negative sign on the number 5. This worksheet reinforces this distinction by showing both forms.
Think of it as removing a debt: if you owe someone $5 (negative $5) and that debt is removed, you're in a better position. Removing a negative is like gaining, so it works the same as adding. Mathematically, the two negatives 'cancel out': 10 - (-5) = 10 + 5 = 15. Use this worksheet's easy problems to practice until this rule feels natural.
The most reliable method for 6th graders is to work the problem in reverse. If they calculated 7 + (-3) = 4, they can check by seeing if 4 - (-3) = 7. They can also use a number line to visually verify their jumps land at the correct spot. For this easy worksheet, reverse checking catches most careless errors.

Both are important. At the easy level, understanding through visual models (number lines, thermometers) should come first, which helps memory stick better. Once they see *why* a rule works through repeated visualization, memorizing the rule becomes a shortcut rather than meaningless symbols. This worksheet supports both by encouraging drawings alongside written answers.
