## Angles

Discover our collection of GCSE angles lessons, activities, powerpoints and notes. These resources are hand-picked by the Tes Maths Panel for their relevance to the 9-1 specifications - use them for planning, homework and revision.

This page contains the very best resources for teaching sections G1, G3, G6 and G10 from the GCSE maths specification (first examined in 2017), combining structured lessons and engaging activities. Angles have always been a staple of the GCSE, but like most topics they have seen a ramp up in challenge in the latest specification. These resources offer up a variety of ways of tackling this key area of mathematics.

#### I Have. Who Has? Angles Game

Children are given cards with an angle. They need to measure their angles using a protractor. They will then write the degree on their card. They will then be ready to play the game. Start with any child who will say, 'I have X degrees. Who has X degrees?' Obviously the child who has that number will then take over and repeat the process. All cards are numbered discreetly should anyone get stuck. The game should end with the first child. May I suggest that you laminate these? If laminated, children can use white board markers that will easily wipe off. I hope you enjoy this resource.

Pupils use angle facts to find the missing angles.

#### Parallel lines & angle facts quiz

20 quick questions on angles (largely) in parallel lines. Emphasis on use of correct terminology. Could be done on mini-whiteboards, or otherwise as quiz, rather than flashcards.

#### Notes - Shape & Space - 1. Angle Facts.Powerpoint

A few years ago I wrote a set of notes for pupils and put them on my website. The notes were supposed to be written in a pupil-friendly way, and different to notes students might find in textbooks or elsewhere on the internet. I have converted the notes to PowerPoint slides so you can download them, adapt them if needed, use them in revision lessons or perhaps give your students a set to take home with them to help them prepare for exams. The chances are there will be a few mistakes here and there, so if you spot any please email me & I will correct them. Hope they are of use!

## Bearings

#### Bearing Lesson 3 Parts - Interactive

A 3 part interactive lesson 1. Angle estimating game 2. How to work out bearings. 3. Tick or Trash plenary using the recent volcanic ash cloud. Any improvements please suggest.

#### Bearings - Pirates of the Caribbean themed

Jack Sparrow has hidden some treasure on an island. Students need to follow the bearings to locate the treasure. Answer: Hangman's Tree. Plenary task also uses the map and is a revision aid for other aspects of the angles topic. It is a rolling powerpoint, timings may need to be changed depending on the ability of the group.

Updated to include the solutions! Now includes an Autograph file that students can use to help in their investigation.

#### KS3 Maths: Bearings activity

Classroom Activity. Worksheet with questions, pupils have to draw bearings.Your Students are Captain of an Airbus A320. They will be given a map of Europe, and details of their Flight Plan. They will need to calculate the bearings between European cities, measure the distances travelled between the cities, calculate the time taken, or the average speed, calculate the amount of fuel used, and also the cost of the fuel. Nb. Check printer settings, so that distances travelled are correct

## Circle theorems

#### 2 TREASURE HUNTS - Circle (Angle Theorems)

Each 20 Poster treasure hunt is ready to print (with solution). Pin the posters up around the room. Give the students different starting points and see who can complete the trail first. The answer to each poster is given on the top of the next poster they must go to in the 'hunt'. A great way for getting students discussing and engaged. Treasure hunt 1 is easier than Treasure hunt 2

#### Circle theorems - MATCH UP

These match up cards are for the first few common circle theorems (angle at centre, angle in semicircle and angles in same segment). I introduce circle theorems using nrich's dotted circles as it really emphasises the isosceles triangles. Then I give students this match up. The aim is for students to match up the question to the answer and then the reasons. The reasons are the hardest as there are often many different ways to answer a question. Last time I used it I deleted many of the reasons and got the students to write them down which made it easier and enabled them to practise the necessary skills. Great for a poster and I do love this activity. I once had two non-mathematicians who were observing really going for the match up and getting all the answers right! Please comment if you use it and any suggestions welcome!

#### Discovering Circle Theorems

This collection is aimed at discovering (or rediscovering) the circle theorems. There are some worksheets to walk students through how to use Autograph to investigate the circle theorems. The website has all these Autograph files ready to use for free online (for those without Autograph). The record sheet is to record what they find for each circle theorem, and can be used to make a wonderful display. The powerpoint document is a Collective memory activity on circle theorems, to be projected on the board and for students to try to recreate. Let me know what you think of these resources!
