Stretch

A regular hexagon has side 6 cm. Find perimeter and each exterior angle.

Reveal a worked check after attempting

Perimeter=36 cm; exterior angle=60°.

Deep challenge

A shape is enlarged by factor 3 and its original perimeter is 18 cm. A learner says new area is three times. Correct the reasoning.

Reveal a worked check after attempting

Perimeter becomes 54 cm; area factor is 3²=9, not 3.

Recall & Review: feedback and extension integration

Lesson L032: Geometry checkpoint and feedback

Objective: Use independent geometry evidence to identify misconceptions, complete a targeted repair and demonstrate transfer.

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.
