Writing and Evaluating Algebraic Expressions Guided Notes
A guided-notes packet for 7th graders on writing and evaluating algebraic expressions, with a short Key Concepts box followed by substitution and word-problem practice. Each question includes ruled space so students can show every step of their work.
“create guided notes titled topic 5-1 Write and Evaluate Algebraic Expressions First it shows "A diver descends at -2.5 feet per minute. What is the total depth change after m minutes?" Then "Evaluate each expression for the given variables 3d - 4 when d = 2 (2/3)p + 3r when p = 3/5 and r = 3" "Amy and two friends earn m dollars together a week. They split the money so each friend gets 1/3 of the total. Last week, they earned $963. Amy spent $32.50 of his money on lunch. How much money did she have left after paying lunch?" "9.5d + 12.75c can be used to find the cost of d pounds of salt and c pounds of oil. How much does it cost to 1 1/2 pounds of salt and 2 1/2 pounds of oil?" have space for each question for the students to show work”
Teacher Guide & Tips
- Use as a 45-minute whole-class lesson: project the Key Concepts, model one substitution problem together, then have students complete the rest of the packet in pairs.
- Discussion question: Why does the expression -2.5m make sense for a diver's depth change after m minutes, and what does the negative sign tell us?
- Discussion question: In the salt-and-oil problem, why must you substitute the fractions 1 1/2 and 2 1/2 before multiplying, and what happens if you forget to distribute the coefficients?
- Scaffold for struggling readers: Provide a worked example of substituting d = 2 into 3d - 4, and encourage them to underline each variable and circle the operation before calculating.
- Extension for advanced students: Ask them to write their own real-world situation for 2/3p + 3r and evaluate it for two different sets of values; estimated time for the full packet is about 35 to 45 minutes.
