Multi-age 3–6, mathematics, Year A – Unit 18
This unit develops the big idea that questions can be asked and answered by interpreting data.
Syllabus
Syllabus outcomes and content descriptors from Mathematics K–10 Syllabus (2022) © NSW Education Standards Authority (NESA) for and on behalf of the Crown in right of the State of New South Wales, 2024.
In this 2-week unit, students are provided opportunities to:
- use data in a spreadsheet to create column graphs (Stage 2)
- investigate how data can be interpreted and used to make decisions (Stage 2)
- conduct chance experiments and compare the predicted and actual results where the outcomes are equally likely (Stage 2)
- represent probabilities of outcomes of chance experiments using fractions, decimals and percentages, comparing predicted outcomes with observed results (Stage 3)
- describe, interpret and pose questions about data presented in tables, column graphs, line graphs and timelines (Stage 3)
- investigate how data representations can be misleading or biased (Stage 3).
