Lesson Overview
Dividing Monomials and Applying the Quotient Rule
To divide monomials, divide each part separately: divide the coefficients and subtract the exponents of variables with the same base. For example, 12x⁵ ÷ 4x² = 3x³. The lesson extends this to problems with multiple variables and introduces negative exponents.
The eight-page lesson walks through the division rules with worked examples. Students complete 20 practice problems and check their work using the answer key on page 8.
How to Use This Lesson
1. Review multiplying monomials and the product rule (pages 1–2). Introduce the division rule as its inverse.
2. Work through dividing monomials step-by-step together (pages 3–6). Include problems with multiple variables and negative exponents.
3. Assign the 20 practice problems (page 7) independently. Review answers using the key on page 8.
