Adding and Subtracting Rational Numbers Practice Set
By Anna B.
A leveled 20-problem practice worksheet for 7th graders that builds fluency with adding and subtracting rational numbers, including integers, fractions, and decimals. It opens with a key vocabulary table covering terms like absolute value, opposites, and common denominators, so students can check their understanding before working through the problems.

Teacher Guide & Tips
- Use this as independent practice after a mini-lesson on number lines and the rules for adding and subtracting signed numbers, or as a homework or small-group station activity.
- Discussion question: Why does adding the opposite of a number give the same result as subtracting it, and how can a number line show this?
- Scaffold for struggling readers: Have them sketch a number line for the first several problems and use the vocabulary table as a reference card before attempting each set.
- Extension for advanced students: Ask them to write their own word problem involving a rational number sum where the answer is negative, then explain the reasoning.
- Estimated time: About 40 to 45 minutes for the full set, depending on how many students use the leveled sections.
