Straight Lines and Full Turns - Year 6 Unit of Work

Students learn to find an unknown angle only after identifying the relationship shown in the diagram. The sequence models angles on a straight line totalling 180° and complete turns around a point totalling 360°, then asks learners to use the full sum, give a reason and check each deduction. Contrasting examples show when adjacent angles do not provide enough information.

The 25-page Unit Plan PDF contains a contents page and three-page teacher guide, a colour display, 12 worked example cards, three progressive practice pages with matching red answer pages, a partner challenge with rules, a worked turn and 12 cards, two transfer rehearsals with answers, an independent three-deduction assessment with marking page, and a four-criterion learning evidence rubric. The teacher guide supplies the partner-game key, lesson moves, equipment and differentiation.

The editable PowerPoint teaching presentation has 18 slides. The editable quiz has 26 slides: a title, 12 question-and-answer pairs and a close. A 69-page watermarked Preview PDF combines the Unit Plan, presentation and quiz for inspection.

Learning focus

Recognise a complete straight angle or full turn; name its 180° or 360° total; include every marked sector in an equation; calculate the unknown; check and explain the result; reject an unsupported adjacent-angle inference.

Classroom use

Use the display and worked cards for explicit teaching, the three practice pages for guided-to-independent progression, the cards for partner explanation, the rehearsal pages for feedback and the assessment/rubric for evidence-based next steps. Use physical half/full turns and partially labelled diagrams for access; extend with a justified three-sector line or an invalid claim.

Formats and answers

25-page Unit Plan PDF; editable 18-slide presentation PPTX; editable 26-slide quiz PPTX; 69-page watermarked Preview PDF. Six matching red worksheet/assessment answer pages, a partner-game key and assessment marking guidance are included.

Teacher benefits

The sequence makes the geometric condition visible before arithmetic. Answer pages sit directly after their matching student pages. The rubric records concept, procedure, reason and transfer separately.
