Stretch

A line has equation y=−3x+4. Find its gradient and y when x=−2.

Reveal a worked check after attempting

Gradient −3; y=10.

Deep challenge

A student says a probability of 1.2 is possible because it came from a frequency table. Diagnose the error.

Reveal a worked check after attempting

Probabilities lie from 0 to 1; the favourable frequency or total, or arithmetic, is wrong.

Lesson L052: Cumulative checkpoint 3 and feedback

Objective: Apply and explain earlier graphs, statistics, probability and number independently.

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.

What Went Well (WWW)

I used my working and assessment evidence to identify the exact mathematical step that was secure and the specific misconception that needs attention.

Even Better If (EBI)

I will correct one precise step, explain why the correction works and complete a fresh delayed question without the original scaffold.
