Negative Exponents Practice: 40 Problems for Algebra
A 40-problem worksheet that opens with a clear explanation of the negative exponent rule and a worked example, then gives students practice rewriting expressions with positive exponents and simplifying numerical answers. It builds fluency with reciprocals and exponent properties, and works well as a 30 to 40 minute independent practice block or a warm-up for ninth graders.
Teacher Guide & Tips
- Use this as independent practice right after introducing the negative exponent rule, or as a warm-up at the start of a class on exponent properties.
- Discussion question: Why doesn't a negative exponent make the answer negative? Ask students to explain the difference between 3^-2 and -3^2.
- Scaffold for struggling readers: Have them rewrite the worked example in their own words, then complete the first five problems with you before working alone.
- Extension for advanced students: Ask them to simplify expressions that combine negative exponents with products and quotients, such as (2x^-3)(4x^5) or (a^-2 b^3)^-1.
- Estimated time: About 30 to 40 minutes for all 40 problems, depending on how many students check their work along the way.
