Main – Use the Spreadsheet and emphasise importance of layout. In the method, show the class how to do the ‘checker.’ Afterwards get students to do the worksheet.
Plenary – Get the students to write a paragraph on how they would solve a trial and improvement question.
Sine Rule – Belfast
Sine Rule - Belfast
Mission Brief level 1 – Sine Rule
Mission Brief level 2 – Sine Rule
Mission Brief level 3 – Sine Rule
Mission Brief level 4 – Sine Rule
Lesson Plan:
Starter: Have some trigonometry questions on the board (basic) and play Dad’s Army intro to the class as they enter
Main: Show them the Belfast Powerpoint and ask them what the 4 pictures are off. Tell them about the Belfast Blitz and about the planned Bismarck attack on Harland and Wolff. Get them to arrange the proof of the Sine Rule. Show them an example.
They can choose their own missions.
Plenary: Rate learning objectives, discuss how to tell the different between Pythagoras, Trigonometry and Sine Rule questions
Least Common Multiple – Zebra crossing
Zebra Crossing
While watching two lights beside a Zebra crossing, I noticed they were flashing at different speeds. The one on the left flashed every 3 seconds and the one on the right flashed every 4 seconds.
- If they have both just flashed at the same time, after how many seconds will they both flash together again?
- If another pair of lights flash every 1.5 and 3.5 seconds, when will they both flash together?
- Two lighthouses shine every 14 and 21 seconds, when will they both shine together?

- A watch costs £40 in London or 46 euros in Paris, which is better value?
Pi – Cake
Pi Cake
Above is a Pi Cake….. thanks to one of my year 11′s for baking this!
- The diameter of the cake is 4.5cm, what is the circumference of the cake?
- A larger cake is made that has a circumference of 50cm, what would the diameter of that cake be?
Pythagoras – Cake
Pythagoras Cake
Here’s one way to help you to remember Pythagoras’ Theorem. Thanks to one of my past Year 11 students for making this!
- If the two shorter sides of a right angled triangle are 5cm and 8cm, what would the hypotenuse be?
- If the hypotenuse is 20cm and one shorter side is 4cm, what is the length of the other shorter side?
Route planning – London underground
Underground map
- How would you get from Camden Town to Marble Arch?
- How would you get from Notting Hill Gate to Green Park?
- How would you get from High Street Kensington to Holborn?
Number – Electricity meter
Electricity meter
The electricity meter was read in January and it was 10431. The picture above was taken in June.
- How many units have been used between January and June?
- If each unit costs 25p, how much would the units cost in total?
- It is expected that the house will use 450 unis by next January, what will the meter read then?
Octagon – Stop sign
Stop sign in Frome
Above is a stop sign, it is a regular octagon:
- What is meant by a ‘regular’ octagon?
- What do the angles in an octagon add up to?
- What is the size of each angle in the regular octagon above?
Octagon houses were really popular in the United Stages and Canada in the 1850′s. The reason for this was it maximised the space inside the house, at the same time minimising the perimeter (walls). The best shape for this would actually be a circle but these were difficult to build and furnish.
