Acrostic
• Each card has two definitions.
• One definition is its mathematical meaning and
the other is the meaning in the workplace.
• Your task is to find each of these words.
• When you have all 10 words you will see a further
word written vertically in the shaded squares.

5
Audience Quiz
• What words describe each pair of definitions?

A tool for smoothing wood. A flat surface on a
shape.

• Listen to this story about a dreadful place of
employment in Lancashire.
• The events take place a long time ago and I hope
that there is no employer now who treats workers
like this.
• Every so often in the story there will be a
mathematical problem that you must work out in
your head.

• 2. What was their biggest selling product?
• 3. In which year was the Factory Act?

13
Pattern Pieces
• Our workers are making patchwork quilts by sewing
together triangles of cloth.
• Help the workers find the correct pieces to sew.
• The designer has put mathematical problems on the
pieces.
• Match each problem with its solution to find out
which pieces fit together.

14
Audience Quiz
Here is one of the patterns used on the quilts.
How many triangles of all sizes can you find?
15
Leisure Services
• Help the workers find the correct pieces
• to sew.
• Following a survey of the leisure facilities
you
• are given some graphs.
• The bar graph shows the numbers of people
• who attended recent events. Something has
• been spilt on it and the document is ruined.
• Can you help to work out the numbers?
• The other graph is a pie chart so it is not
clear
• how many people chose each option. Use the
• clues given to find the numbers for each
• choice?

16
Audience Quiz
250 people used these services, the number
attending the concert was half as many again as
the number who used the library.
How many attended the concert and visited
the library?
17
Audience Quiz

The number who chose Sports Hall is twice
the number who chose swimming.
Work out the numbers of people who selected each
option.
Five times as many chose the Pop Concert as chose
the Internet Cafe.
