Teach estimating and measuring length, mass and capacity through a complete Year 7 Core PowerPoint lesson grounded in Sparx M828 question archetypes. Pupils learn to count intervals rather than marks, read calibrated rulers, jugs and mass scales, distinguish exact readings from estimates, select sensible real-world measurements and calculate totals and differences from scale readings.

The editable standalone lesson includes:
• six-question retrieval starter and mirrored answers;
• explicit vocabulary and representation teaching;
• six-question I Do-We Do modelling with three matched instrument-reading pairs and protected teacher modelling space;
• exactly 12 mini-whiteboard AFL checks, each followed immediately by its answer;
• calibrated jug, ruler, linear-scale and circular mass-scale diagrams;
• recognisable real-world pencil, school-bag and bath estimation visuals;
• 12-question structured diagram-based independent practice;
• one-slide three-column Developing, Secure and Greater Depth practice;
• a full-width scale-construction Super Challenge;
• misconception diagnosis, problem solving, challenge and exam-style questions;
• complete checked answers and an exit assessment.

Designed as a bold, projection-readable, print-free classroom resource. The required information is visible on each pupil task slide, with explicit units and complete question wording. The PowerPoint is fully editable.
