  1. Calculations and checking

  2. Bell work • Boot your lap tops up • Show me boards • Count down...

  3. Calculations and checking

  4. WALT Use and apply our knowledge of ‘BODMAS’ to work out areas of regular and irregular shapes WILF L3 – to be able to solve problems with two or more steps L4 – as above but to do this in your head (with a few jottings!) L5 – as level 4 but to also be able to work with fractions, decimals and percentages Calculations and checking

  5. Calculations and checking – task 1 • Show me boards HWK – On the VLE • Multiplication tables..... • List all of the prime numbers between 1 and 100 • Memorize the first 10

  6. Do you know what this is?

  7. 2012 – Olympic village...

  8. What it looks like now....

  9. Your task..... Car Parks

  10. Tarmacadam

  11. Your tasks...... 1 - In your exercise books put the date and title. 2 - Find the Olympic Village site on ‘Google maps’ 3 - Estimate by using the scale on the map the perimeter of each shape 4 – Work out the area of each shape 5 – Work out the cost of laying the tarmac..

  12. Testing the learning On your white boards.......

  13. Task1 – find it! • Log onto the VLE – my lesson PowerPoint. • ‘2012 Olympic stadium London’ • Click on ‘larger map’ • Look north of ‘A’ and use the zoom tool to view. • Look at the scale..... • 1cm => 200m?

  14. Your task..... Car Parks 1cm = 200m

  15. Task 2 – the perimeter... 1cm = 200m What is the perimeter? – work it out How will the scale help you? Draw the shapes to scale in your books

  16. Task 2a – area...car park 1 1 2 1cm => 200m Regular or irregular? How many rectangles? How many areas? How many calculations? Use your scale drawings..

  17. Test the learning... Mini white boards...

  18. Task 2b – area...car park 2 1 2 1cm => 200m Regular or irregular? Do you know the equation? How many triangles? How many areas? How many calculations?

  19. Area of a triangle... Perpendicular Height Base Area of a triangle = ½ X base X perpendicular height 1

  20. Costs....1 Tarmac costs £55 per tonne 1 tonne of Tarmac will cover 0.5 m2 How many tonnes of tarmac will you need?

  21. Costs....2 If kerb stones cost £5.50 per meter, how much will the kerbing cost?

  22. Costs....3 Labour costs £10 per hour per person, if 50 people work on this project for 4 weeks working from 9am to 5pm 6 days a week , how much will the labour cost?

  23. Total cost What will the total cost be? (Cost 1 + cost2 + cost3 =total cost)

  24. Test the learning... Mini white boards...

  25. WALT Use and apply our knowledge of ‘BODMAS’ to work out areas of regular and irregular shapes WILF L3 – to be able to solve problems with two or more steps L4 – as above but to do this in your head (with a few jottings!) L5 – as level 4 but to also be able to work with fractions, decimals and percentages Calculations and checking
