UNIT NAME: Recognising, collecting and recording data                YEAR LEVEL:  3
SEMESTER:   3                 NUMBER OF WEEKS/LESSONS:       4 weeks/20 lessons              CONTENT STRAND (National Curriculum): Data representation and interpretation
Targeted student learning outcomes & elaborations:
• Identify questions or issues for categorical variables. Identify data sources and plan methods of data collection and recording (ACMSP068)

• Collect data, organise into categories and create displays using lists, tables, picture graphs and simple column graphs, with and without the use of digital technologies (ACMSP069)

• Interpret and compare data displays (ACMSP070)

Elaborations:

- Refining questions and planning investigations that involve collecting data, and carrying out the investigation. Narrowing focus questions

- Exploring meaningful and increasingly efficient ways to record data, and representing and reporting the results of investigations
- Comparing various student- gathered data representations and describing their similarities and differences

Big mathematical ideas/concepts:
• Data collections are planned to investigate their own and others’ questions

• How to collect and organise data

• Data displays represent collected data

• Elements of data displays

• How to create data displays

• How to interpret data displays using elements of displays

• Identify and clarify as issue of interest or question to be investigated

• Us observation and questioning as ways of gathering data

• Suggest and use different recording methods to collect data

• Classify data into suitable categories

• Determine the method for data collection

Prior knowledge/skills:
• Ability to identify picture and column graph

• Basic understanding of column and picture graphs

• Collecting data using a tally

• Carroll Diagram
