Lesson Overview
Distributing and Combining Like Terms to Simplify Expressions
When an expression contains parentheses, distribute first: multiply the factor outside the parentheses by each term inside. Then identify like terms in the resulting expression and combine them. For example, 3(2x + 4) + x simplifies to 6x + 12 + x = 7x + 12.
The nine-page lesson reviews combining like terms and the distributive property separately, then integrates both skills. Students complete 20 practice problems and check their work using the answer key on page 9.
How to Use This Lesson
1. Review combining like terms rules (pages 1–2). Reinforce sign awareness and term identification.
2. Review the distributive property and practice distributing (pages 3–5). Use numeric and variable examples.
3. Combine both skills: distribute then combine like terms together (pages 6–7). Assign the 20 practice problems (page 8) independently. Review answers using the key on page 9.
