Writing Equations from Word Problems: Grade 8 Study Guide
A study guide for 8th graders that teaches how to translate word phrases into algebraic expressions and equations, aligned to Georgia's 8th grade math standards. It builds skills in identifying key terms like variable, initial value, and rate of change, and in decoding phrases such as "sum," "difference," "product," and "per" into the correct operations. It works well as a focused review or practice block for students who are learning to model real situations with linear equations.

Teacher Guide & Tips
- Use this as a 30-45 minute mini-lesson or independent review before a unit test, starting with the key terms and phrase-to-operation chart so students build vocabulary before tackling problems.
- Discussion question: Why does the phrase "less than" reverse the order of the numbers when writing a subtraction expression, and how can students check that their order is correct?
- Scaffold for struggling readers: Have students highlight the operation keywords in each word problem first, then write the equation one phrase at a time before combining the pieces.
- Extension for advanced students: Ask them to write a word problem of their own that models a rate of change with an initial value (y = mx + b), then trade with a partner to translate each other's equations.
- Estimated time: about 35 minutes including guided practice on the chart and two or three worked examples.
