THE TASKS
CARRIE’S BUNGALOW
Carrie has just moved into a bungalow.
She needs to do some work on the bungalow before she can furnish the
rooms.
There are three tasks in this activity.
The tasks involve using working with scales and diagrams.
Task 1 is about insulating the hot water pipes in the bungalow.
Task 2 is about furnishing the main bedroom.
Task 3 is about working with scales of furniture.
Work together in small groups to complete the tasks.
When you have completed the tasks you should compare your findings with other
groups.
Remember you must be able to justify your answers.
Task 1
Insulating the hot water pipes
Carrie needs to insulate the hot water pipes under the floorboards which carry
hot water to central heating radiators.
This will save her money as it will stop a lot of the heat is being wasted.
The diagram shows the type of insulation Carrie must use on the hot water
pipes.
The floor plan on the following page shows where the hot water pipes run
under the floorboards in Carrie’s bungalow.
It also shows where the radiators and the taps are.
Carrie uses the plan to work out the total length of pipe she needs to lag.
What you must do:
 Find the total length of pipes that need insulating.
 Decide how much insulation Carrie needs to buy.
 Remember: you only need to measure the lengths of the hot water pipes
that connect the radiators.
Window (green)
The insulation comes in two metre lengths and is sold in packs of three.
 How many lengths of insulation does Carrie need?

How many packs of insulation does Carrie need to buy?

You can use this scale marked out in squares to
help you work out the lengths of hot water pipes
in the bungalow in metres.
Scale ruler
You need to mark each2division.
The scale is:
squares to 1m
2 squares represent 1 metre
The first four are done for you.
Now cut it out and use it to measure the lengths
of pipes shown on the floor plan of the
bungalow.
Task 2
Furnishing the main bedroom
Carrie wants to buy some new bedroom furniture.
She has the measurements of the furniture she wants and needs to
check this will fit in her bedroom.
This is how she does it.
1. Carrie makes a plan of her bedroom.
(She works out the measurements from the plan of the bungalow)
2. She makes a plan of each piece of furniture.
Carrie only has to draw the base of each piece of furniture, (this
will show how much of the floor it will cover).
3. Carrie uses a scale of four squares to 1 metre, for the plan and the
drawings.
4. She places the furniture pieces on the floor plan to decide the
layout.
Conditions
1. No furniture must be put against the radiator.
2. There must be gap of at least 1 metre around the sides and bottom
of the bed.
Remember to leave room for the door to open.
Show how Carrie can arrange the furniture in her bedroom
Use square paper to make a plan of the bedroom and the drawings of
the furniture.
Cut the pieces of funiture out and show how they fit on the scale
diagram of carries’ bedroom.
These are the pieces of furniture Carrie wants in her bedroom.
Bed
width and length
150cm x 200cm
Wardrobe
width and depth of the wardrobe.
200cm x 75cm
Dressing table
width and depth of the dressing table.
150cm x 50cm
Chest of drawers
width and depth of the chest of drawers.
100cm x 50cm
Use the square paper on the following page to draw an outline of the
main bedroom. Use a scale of 4 squares to represent 1metre.
Use the same scale on this square paper to make drawings of the
furniture for the bedroom.
Task 3
Find the Scale
Can you match the drawings with the furniture and the scale used?
You are given cards showing 12 scales and pictures of 8 objects.
Can you match the scales with the scale drawings of the objects?
Not all the scale cards are needed.
Remember:
Check the units used!
You may have to convert some of them.
You can use the strips below to work out what each division should be for
the different scales used in this task.
The strips have been started for you.
They can be cut out for use with this task.
