Collecting and Organising Data

This topic empowers your pupils to become data detectives, asking their own questions and finding the answers using maths. They will discover how to bring order to information and tell a story with numbers.

Our Class Favourites Survey

Pupils work in pairs to design a simple survey question with four or five set answers, such as 'What is your favourite season?'. They then survey their classmates, record the answers using a tally chart, and present their findings in a final table.

Explain the steps you would take to conduct a survey about your classmates' favourite sports.

Facilitation Tip

Model how to create a question with limited choices first to avoid having too many different answers to manage.

What to look for

Observe pupils as they collect data in pairs. Check their tally charts for correct grouping and ask them to explain what their data shows so far.

The Lunchbox Investigation

For one week, pupils observe and tally the types of fruit they see in their classmates' lunchboxes. Each day they add to their tally chart, and at the end of the week, the whole class compiles the data to see which fruit was the most common.

Compare using a simple list versus a tally chart to record survey results.

Facilitation Tip

Create a large master chart on the whiteboard where pupils can add their daily tallies for everyone to see.

What to look for

Provide pupils with a set of raw data (e.g., a list of 20 answers to 'favourite ice-cream flavour') and ask them to independently create a tally chart and a final table to represent it.

School Grounds Data Hunt

Take the class outside to the school grounds or yard. In small groups, pupils are given a list of things to find and count using tallies, such as the number of benches, types of trees, or colours of flowers.

Identify a question you could investigate in your school and describe how you would collect the data.

Facilitation Tip

Provide each group with a clipboard and a pre-made sheet to keep them focused on the task.

What to look for

Give pupils a simple checklist to review their own table: 'Does it have a title?', 'Are the columns labelled?', 'Are my totals correct?'.

A few notes on teaching this unit

Begin by modelling the entire process with the whole class using a simple, relatable question like 'What is our favourite colour?'. Fill in the tally chart on the board together, emphasising the 'five-bar gate'. Then, let pupils practice in pairs with a structured task before they try creating their own survey from scratch.

By the end of this topic, your pupils will be able to design a simple survey, gather data using tally marks, and neatly organise their findings in a table.

Watch Out for These Misconceptions

• Pupils forget to use a diagonal line or 'gate' for the fifth tally mark and just continue with vertical lines.

  Explain that the 'gate' across the four lines is a special way to group a set of five, which makes counting up large numbers much faster. Practice counting in fives using bundles of lollipop sticks or by chanting while drawing tally gates on the board.

• When creating a table, pupils mix up the rows and columns, putting categories where the numbers should be.

  Emphasise the importance of titles and headings for both columns and rows before any data is entered. Show them examples of familiar tables like a school timetable to reinforce how they are structured.

• Pupils think that a survey has to ask everyone in the world, not just a small group.

  Clarify that a survey is designed to find out information about a specific group, which for them is their class. The results tell a story about 'our class', not about every child in Ireland.
