Collecting and Visualising Data

Collecting and visualising data is where computer science meets real-world decision-making. In 6th Year, students move beyond simple tally charts to using digital tools for data collection and analysis. This topic is a direct application of the Data strand in the NCCA Primary Mathematics Curriculum, focusing on representing and interpreting information. Students learn that data can tell a story and help us solve problems in our community.

Inquiry Circle50 min · Small Groups

Inquiry Circle: The Great Class Survey

Groups design a digital survey (using a tool like Google Forms or MS Forms) on a topic like 'Favourite School Lunch.' They collect the data, then use a spreadsheet to create different types of charts to see which one tells the story best.

Gallery Walk: Data Detectives

Display several different graphs (some clear, some misleading). Students move in pairs to 'interrogate' the data: What is this telling us? Is anything missing? Why did the creator choose this type of graph?

Think-Pair-Share: Infographic Design

Students are given a small set of data about Irish wildlife. They must sketch an 'infographic' on paper that uses icons and colour to make the data easy to understand, then explain their design choices to a partner.

A few notes on teaching this unit


Watch Out for These Misconceptions

  • Any graph will work for any data.

    Students often default to bar charts. Use a station rotation to show that some data (like changes over time) is better suited to line graphs, while parts of a whole are best shown in pie charts.

  • Data is always 100% accurate.

    Explain that data is only as good as the collection method. Use a peer teaching activity to discuss 'bias', for example, if you only survey your friends, your data doesn't represent the whole school.
