1. Unit 6 - Numeracy 6.1a – Decorating and calculating costs

2.  Your plans are coming along nicely:  You’ve decided what ‘The Ruin’ will be used for  You’ve created advertising for it (both static and live action)  You’ve come up with mood boards to show how it may look  Now you need to look at decorating it and how much this will cost. 2 So far, so good!

3.  You have decided to hire an interior designer to bring your ‘mood board’ ideas to life.  However, before that person starts work, they have asked that all rooms have the following:  A basic plain coat of paint  Dado rails in main rooms  Skirting boards in all rooms 3 So far, so good!

4.  In order to carry out this task you need to know how to calculate AREA and PERIMETER:  Perimeter is the distance all the way round a 2D shape  Area is the amount of surface the 2D shape covers 4 Area and Perimeter

5.  Laying turf in the garden?  Putting a border up in your bedroom?  Putting a fence up around a vegetable patch?  Working out how many cars will fit in a field for a Car Boot Sale? 5 Area or Perimeter?

6.  Area is calculated by multiplying length by width (some people say breadth – but this is the same thing!)  So the formula for working out area is  L x W (or L x B)  The answer will always end with ² (this means squared) 6 Area Recap

7.  So the area of this shape would be:  L x W  3.5 x 2 = 7m² 7 Area Recap 2 m 3.5 m

8.  Perimeter is calculated by adding up the length of all sides of the shape:  L + W + L + W  Or you can show it as:  2L + 2W 8 Perimeter Recap

9.  So the perimeter of this shape would be:  L + W + L + W  3.5 + 2 +3.5 + 2 = 11m Or:  2L + 2W  (2x3.5) + (2x2) = 11m 9 Perimeter Recap 2 m 3.5 m

10. Using the scale drawing you have been given, you need to carry out the following tasks:  Work out how much paint you will need  Work out how much dado rail you will need  Work out how much skirting board you will need and finally…cost it all out. 10 Task

11. You can tackle this in different ways:  Everyone can calculate everything – and compare answers to check for accuracy  Everyone takes on a room to cost – and shares this with everyone else to work out total costs  Everyone takes on an item to cost (e.g. the dado rails) and then shares this with everyone else to work out total costs It’s up to you… 11 Tackling the task

12. If you completed the task quickly – have a go at this…  The sitting room and lounge need to be carpeted:  Cost up a carpet that fits in with your ‘mood board’ ideas and include underlay Or:  The patio needs new slabs laid  Cost this up ensuring as little wastage as possible 12 Extension Activity

13.  You’ve calculated the costs for only a small section of ‘The Ruin’  Do you think renovating such an old building is going to be expensive?  What factors should you consider in relation to this renovation? 13 Review
