Today we will be learning:
• how to carry out a survey
• how to organise results and show them as a bar chart.
Mental Activity
We are going to play a game to practise adding and subtracting.
We are going to count around the class.
Here are the rules.
• The first person adds 5 to a number.
• The next person subtracts 1.
if we start with 4
the next number will be 9
then 8
then 13
then 12 and so on.
For example:
Start on 5.
Give the next number in the pattern before the answer appears.
5 10 9 14 13 18
22 21 26 25 30
29 34 33 38 37 42
41 46 45 50 49 54
53 58 57 62 61 66

Main Activity
Today we are going to be looking at data.
What does the word “data”
mean?
Data is another word for
information.
Handling data includes:
• collecting the data
• displaying the data
• using the data to help us to answer questions.
A class of 30 children were asked to choose a favourite colour from red, yellow or blue.
If they did not like any of the colours, they could choose “None of these”.
Their votes were collected using a tally chart.
How many does each tally show?
7
Which was easier to count?
Why?
How many children voted for each colour?
None of these

We are going to make a bar chart to show the results.

How many squares
tall will our tallest bar
be?
The horizontal and vertical lines are called axes.

Group Work
Carry out a group survey and make a tally of the results. Draw a bar chart to show the data.
Practise answering questions using information from bar charts.
Work with a partner. Write four questions that could be used to carry out a survey.
