By the end of this unit of work you should be able to do the following:
- Identify, name, measure and draw six different types of angles (acute, right, obtuse, straight, reflex and revolutions)
- Identify, name, measure and draw six types of triangles (acute, right, obtuse, equilateral, isoceles and scalene)
- Identify and name six different quarilaterals (square, rectangle, rhombus, parallelogram, trapezium and kite)
- Identify and draw perpendicular and parallel lines
- Identify and calculate vertically opposite, alternate, corresponding, complementary, supplementary and co-interior angles.
- Calculate missing angles in triangles and quadrilaterals.
- Accurately draw regular polygons and calculate angles in regular polygons.
Each of the following activities matches with specific learning outcomes.
Acute and Obtuse angles – Guess the random angle
Measuring Angles – What’s my Angle?
Naming and measuring angles – Kidport Measuring Angles
Vertically opposite, corresponding and alternate angles – Exploring relationships of Angles
Types of triangles – sort into Venn diagrams – Sorting Triangles
Angles in a triangle add to 180 degrees – Exploring Angles: Resize a triangle
Calculate angles using opposite, complementary and supplementary angles – Exploring triangles.
Go to Voicethread and add your voice or text comments about triangles.

In term 2, Year 6/7 students will be starting a unit on Angles. Why is it important to learn how to identify, measure, draw and name angles? You can see in the picture above that angles are all around us in the built environment. Here are just some of the jobs where knowing about angles is necessary: Architect, Builder, Carpenter, Cartographer, Engineer, Fashion Designer, Graphic Designer, Landscape Gardener, Pattern-maker, Pilot, Surveyor and Welder. Sportspeople, such as golfers, soccer players and snooker players also use angles. Perhaps you can think of some others? Please add them to the comment space below.
Over the next few weeks your class will be working in three groups, rotating through diferent activities. One group will be working on Rotograms, another group will be using their netbooks to explore some ICT tasks and the third group will be doing teacher-led activites with me. You will need a protractor, a ruler and a compass for this unit of work. If you are in the ICT group you can choose from the following activites: The Year 7 Maths and Science wiki has links to sites where you can learn more about angles. If you go to the FUSE site and search for the resource package 4J2LK7, you will find some more interactive games and learning tasks to use on your netbooks. BBC KS3 Bitesize has Revision pages, an activity and a test about angles. For each of the sites you visit, you should write a short review of how helpful the activity was for your learning.
- What did you learn?
- Was the activity easy or challenging?
- Would you recommend the site for other students wanting to learn about angles?
- How would you rate the site out of 10? (where 10/10 is awesome!)
