Are you teaching Year 5 or 6 pupils about acute, obtuse and right angles, and how to measure them accurately using a protractor? This fully resourced UKS2 maths interview lesson is perfect for teaching this complex topic in a clear, engaging, and mastery-focused way – and has been rated Outstanding in observation.

Lesson Focus:
Pupils learn to identify different types of angles and accurately use a protractor to measure them, using clear, structured success criteria and practical reasoning tasks. This lesson is ideal for interviews, Ofsted inspections, or any formal observation requiring strong subject knowledge and visible pupil progress.

Learning Objective:
To accurately measure angles using a protractor

Success Criteria include:

• Lining up the bottom of the protractor with one line of the angle
• Ensuring the vertex is at the centre of the protractor
• Reading the correct set of numbers based on the 0 mark

What’s included:
✔ Fully resourced PowerPoint presentation with modelling and visual prompts
✔ Cold task starter to check prior knowledge
✔ Step-by-step teacher modelling and guided input
✔ “Simon Says” angle game for physical engagement and recall
✔ Angle eaters and differentiated worksheets (e.g. estimating and measuring angles)
✔ Hot task for confident learners to complete independently during input
✔ Show-it tasks, table display cards, and challenge questions
✔ Plenary reflection to revisit success criteria and evaluate learning

Why teachers love it:
✔ Encourages deep understanding of angle types and measurement
✔ Differentiated for a range of abilities – from emerging to greater depth
✔ Promotes reasoning and problem solving, not just procedural fluency
✔ Ideal for a 30–60 minute observation or interview lesson
✔ Memorable, engaging, and clear modelling throughout

Perfect for:

• Year 5 / Year 6 maths lessons
• Interview demonstration lessons
• KS2 maths observations
• Reasoning and problem-solving tasks
• Exceeding / greater depth mastery in geometry
