Coaching Prompts for Common Student Errors
Included the Chicago Fact
What Happened: Student got pulled in by the big number (106 degrees). Coach: "If you erase Chicago, does the paragraph still explain why cities get hot? Focus on all cities, not just one day."
Added Opinions
What Happened: Student wrote "Hot cities are awful" or "I love planting trees." Coach: "Be a scientist or reporter! Tell only the facts the author gave us without sharing your feelings."
Forgot the Solution
What Happened: Student only wrote about cities getting hot and skipped the trees/roofs. Coach: "Look at sentence two of your summary. Can you tell what people are doing to solve the heat problem?"
