Recording and Presenting Data

Overview

In this 60-minute session, Year 5 pupils will consolidate their knowledge of measuring length by recording their heights in centimetres, organising this data into charts, and then transferring it onto a line graph using the j2data software. This hands-on, collaborative lesson supports the development of data handling and presentation skills, linking measurement to statistical representation, as outlined in the Northern Ireland Curriculum for Mathematics.

Northern Ireland Curriculum: Mathematics and Numeracy (Primary)

Learning Area: Using Mathematics

• Attainment Target 1: Using and Applying Mathematics
  • Pupils become confident in collecting, organising, and presenting data in a meaningful way.
• Number and Algebra Strand
  • Understand and use measures, including length (cm).
• Using Mathematics Across the Curriculum
  • Develop cross-curricular links by using ICT tools (j2data) to present data.

Specific Learning Objectives

By the end of the lesson, pupils will:

• Estimate and accurately measure their own height in centimetres.
• Record individual measurements systematically in a chart.
• Transfer collected data into a line graph using ICT (j2data).
• Interpret and discuss findings based on the line graph.
• Collaborate effectively in small groups, communicating mathematical ideas clearly.

Lesson Plan

Materials Needed

• Measuring tapes marked in centimetres (enough for pairs of pupils)
• Clipboards, data recording sheets/charts
• Computers or tablets with access to j2data
• Whiteboard and markers

Structure

Time	Activity	Description
0-10 mins	Introduction & Review	Recap measurement techniques, review units of length (cm). Discuss the importance of recording data accurately. Demonstrate how to measure height properly using a tape measure.
10-25 mins	Measuring Heights & Recording Data	Pupils work in pairs to measure each other’s heights in centimetres, recording their partner’s height on a prepared class chart. Ensure accuracy and neatness. Pupils estimate first, then measure to verify.
25-40 mins	Creating a Line Graph (j2data)	Teacher models entering the class data into j2data, demonstrating how to create a line graph. Pupils then use devices to input their class data into the software independently or in pairs.
40-55 mins	Interpretation & Discussion	Guide pupils through interpreting the line graph. Prompt discussion: Which heights are most common? Any outliers? How does the visual data compare to the original chart? Discuss why visual presentations help understanding.
55-60 mins	Plenary & Reflection	Quick quiz or verbal recap on the steps taken today and the value of clear data presentation. Pupils share what they found interesting about measuring and graphing. Set a related challenge (e.g., measure a family member at home).

Differentiation & Support

• Support: Pair less confident pupils with stronger peers when measuring and inputting data. Use clear, step-by-step modelling for ICT activities.
• Extension: Challenge more able pupils to calculate the range and mode of heights or to present data in an additional graph type (e.g., bar chart) within j2data.

---

Assessment Opportunities

• Formative: Observe pupil engagement during measurement and data entry. Check accuracy of recorded heights.
• Summative: Review completed line graphs for correct data plotting and presentation. Assess pupil contributions during discussion for understanding of data interpretation.
• Self-Assessment: Pupils reflect verbally or in writing about what they learned about data recording and presentation.

Cross-Curricular Links

• ICT: Use of j2data software to create and manipulate graphical data.
• Literacy: Use mathematical vocabulary such as "estimate," "measure," "centimetres," "graph," "axis," and "data." Describe and explain findings.
• Personal Development: Develop skills in teamwork, communication, and accuracy.

Teacher Tips

• Ensure safety during height measurement, particularly around standing against walls or furniture.
• Emphasise the excitement of seeing their own data "come to life" in a graph—use this to motivate pupils.
• Use questioning to deepen thinking: “What can this graph tell us that the chart cannot?” or “Why might someone use a line graph instead of a table?”
• Record and save pupil graphs in j2data for continuity and revision in future lessons.

This lesson will empower pupils to see measurement as part of a broader mathematical picture, combining practical skills with ICT and data interpretation, fulfilling key competencies of the Northern Ireland Curriculum.
