1 Year 2 | Statistics Strand CONTENT DESCRIPTOR AC9M2ST01 - Acquire data for categorical variables through surveys, observation, experiment and using digital tools; sort data into relevant categories and display data using lists and tables. ELABORATIONS * Collect simple categorical data (e.g., favourite fruit, pet type). * Sort and display results using tallies, tables, or digital graphs. * Use classroom and online tools to represent and interpret data. PRIOR KNOWLEDGE Year 1 (AC9M1ST01): Students record categorical data using drawings or tally marks but have limited experience classifying or analysing patterns. * Recognise that data describe familiar categories (e.g., colour, animal type). * Gather data informally through observation or simple questions. * Focus on recording rather than sorting or interpreting. NEW CONCEPTS * Categorical variables: Data that can be grouped by labels (e.g., colours, animals). * Sorting and classification: Organising data to find patterns. * Representation: Recording and interpreting results using lists, tallies, or tables. NEW STRATEGY / SKILL * Designing and conducting class surveys or observations. * Sorting, recording, and displaying data digitally (e.g., Google Sheets, Seesaw, ABCya). * Interpreting and explaining which category appears most or least often using reasoning language. HOW TO TEACH IT - GENERALISED ACTIVITY IDEAS (YEAR 2 STATISTICS) * Inquiry-based surveys: Students collect real data (e.g., favourite fruit
