L100 · Allow 10–15 minutes for learners ready to move on. Answers are available after an attempt.
Rework 5/6−1/4 without a calculator and simplify.
10/12−3/12=7/12.
A learner adds denominators in 2/3+1/4 to get 3/7. Explain and correct.
Use common denominator 12: 8/12+3/12=11/12.
Lesson L100: Paper 1 feedback and repair
Objective: Interpret feedback on mock Paper 1 and repair a priority misconception.
60-minute structure: 0-7 Connect & Check; 7-14 Share; 14-25 Present/model; 25-44 Apply route choice/practice; 44-52 independent exam-style check; 52-60 Recall & Review, WWW/EBI and next step.
I used my working and assessment evidence to identify the exact mathematical step that was secure and the specific misconception that needs attention.
I will correct one precise step, explain why the correction works and complete a fresh delayed question without the original scaffold.
Stretch: Rework 5/6−1/4 without a calculator and simplify.
Deep challenge: A learner adds denominators in 2/3+1/4 to get 3/7. Explain and correct.
