This document discusses common issues students have when solving linear equations and provides examples. It analyzes typical work samples to identify errors, like assuming subtraction is commutative or only considering positive numbers. Feedback questions are created to help students understand where they went wrong and find the right solution.

- 1. Solving Linear Equations Professional Development
- 2. Agenda Discuss formative assessment Analyze 5 typical work samples What feedback would you provide? Create feedback questions for class
- 5. Are Amy and Ben correct? If not, where have they gone wrong? Amy: Ben: What is your answer to the question?
- 14. Common Issues Assumes that subtraction is commutative For example: Assumes that 5 x = 6 is the same as x 5 = 6 and gives a value of x = 11 Considers positive numbers only For example: Assumes that Ben is correct Fails to explain why they are incorrect Uses equal sign incorrectly For example: The student writes 5 x = 6 = x = 1.
Editor's Notes
- #2: Identify the formative assessment that is the basis of the PD (page 1 only)Get teachers to analyze 5 work samples representative of typical students. Pose the question: Suppose you were posed with these work samples. What feedback would you provide?Write feedback questions for class.
