# Stage 3, mathematics, Year A – Unit 05

This unit introduces the big idea that questions can be asked and answered by interpreting data.

Students are provided with opportunities to:

• collect categorical and discrete numerical data by observation or survey
• represent and interpret data presented in tables, column graphs and line graphs, with and without the use of digital technologies
• recognise, represent and order numbers in the millions and decimals.
