Distributive Property Combining Like Terms Lesson
Teach students to simplify expressions using two strategies in sequence: apply the distributive property, then combine like terms. The lesson builds on both skills and connects them into one fluent simplification process. Includes 20 practice problems and answer key.

Lesson Overview
Using the Distributive Property and Combining Like Terms
The distributive property states that a(b + c) = ab + ac. After distributing, the resulting expression often contains like terms that can be combined. For example, 2(3x + 4) + 5x distributes to 6x + 8 + 5x, which simplifies to 11x + 8. The lesson teaches this two-step process with clear worked examples.
The seven-page lesson walks through the distributive property and like-terms combination with increasing complexity. Students complete 20 practice problems and check their work using the answer key on page 7.
How to Use This Lesson
1. Review the distributive property (pages 1–2). Show how to expand expressions before combining.
2. Work through examples that require both steps together (pages 3–5). Practice distributing first, then simplifying.
3. Assign the 20 practice problems (page 6) independently. Review answers using the key on page 7.
