Missing angles and lengths

  • Year group: Year 6
  • Term: Summer
  • Topic: Geometry
  • Duration: 1 weeks
  • Keystage: KS2
  • Age Range: 10 to 11 yrs
  • Unit can be taught out of sequence: Y
  • Week Range: 2

In this chapter, pupils use angle properties to find missing angles.

Building on learning from previous chapters, pupils make deductions about missing angles using angle sum facts, as well as other properties, and relate these to missing number problems. Additionally, they recognise angles where they meet at a point, are on a straight line or are vertically opposite.

Mathematics Mastery

Missing angles and lengths

Developing pupils’ problem solving skills is a key element of the Mathematics Mastery programme.

This topic focuses on missing angles and lengths and can be used in two ways. 1. To support parents with their child(ren)’s learning at home, helping them to develop their mathematical understanding beyond the classroom environment. 2. For teachers to use this resource as a basis for a classroom activity, helping pupils to practise and consolidate their understanding.

• Each task is accompanied by guidance to support parents with concepts and methods they may be less familiar with
• For the classroom, you can introduce this as an independent task or in mixed attainment pairs to encourage mathematical discussion

Missing angles and lengths

Deepening pupils’ understanding of key mathematical ideas is a core element of the Mathematics Mastery programme.

Our Key Constructs highlight the essential mathematical concepts all pupils are expected to grasp within each year group, with accompanying guidance for assessing pupil progress.

Our Key Constructs are closely aligned to the National Curriculum’s objectives. We know these can be tricky to evidence, so we’ve included an example task for each concept, as well as ideas to support slower-graspers and depth tasks to challenge higher-attaining pupils.

• Pupils should work through the tasks independently
• Teachers should incorporate the CPA approach to support pupils’ learning
• Opportunities for depth and scaffolding are built into each task

Missing angles and lengths

Enabling pupils to develop their mathematical reasoning skills through independent work is a key element of the Mathematics Mastery programme.

This activity explores the concept of missing angles and lengths

• Pupils should complete these tasks using concrete manipulatives as part of the CPA approach
• Pupils should be encouraged to explain their working in full sentences
• These tasks may be adapted with pupils working in pairs to encourage mathematical discussion

Investigating Angles

These worksheets can be used in a single carousel/round robin-style lesson or separately. The left half of each is an investigation of an angle rule and the right half has missing angle problems related to that rule. The missing angle problems increase in difficulty.
I divided my class into colour groups based on ability level to investigate each rule. I used envoys and 'rainbow groups' (1 person from each colour group) to share what each pupil had learnt, before doing a 4-question test at the end of the lesson.
