Teach converting units of time with a carefully sequenced Year 7 Core PowerPoint lesson built around I Do–We Do–You Do pedagogy. Pupils learn to move accurately between seconds, minutes, hours, days and weeks, selecting multiplication or quotient-and-remainder methods and checking that each converted value is reasonable.

The lesson is fully editable, standalone and print-free, making it suitable for whole-class teaching, cover lessons, intervention or revision.

Included:
• six-question retrieval starter with mirrored answers;
• complete vocabulary and unit-structure teaching;
• three matched I Do and We Do examples with dedicated modelling space;
• three revealed I Do solutions and one consolidated We Do answer slide;
• exactly 12 diagnostic mini-whiteboard questions, each followed immediately by its answer;
• 24-question minimally different practice with purposeful variation;
• one-slide Developing, Secure and Greater Depth practice plus a full-width Super Challenge;
• self-contained error analysis, comparison and open-ended reasoning;
• problem solving, challenge and exam-style questions;
• complete checked answers and worked solutions throughout.

All numerical choices have been designed to produce suitable exact answers without uncontrolled calculator decimals. The lesson uses clear bracketed numbering, correct time units and projection-friendly typography throughout.
