Lesson 1 – Data Collection
- Invite students to respond to the following questions:
- ‘How can we find out which animal is the most common pet for students in the class?’
- ‘What do we need to do to find the answer?’
- Encourage students to consider effective methods of collecting and usefully recording information by asking the following:
- ‘Who needs to be asked?’
- ‘What do we need to ask them?’
- ‘How would we remember the information that we gather?’
- ‘How should we collect the information so that we can remember it?’
- Create a record sheet/table for data collection
- create a record sheet similar to appendix 1
- Once this data has been collected, students can begin to display that data.
- Explain that there are many different ways to present data. For example, we can use colours, shapes, pictures or numbers to present our data so that people can see patterns.
- Explain that we are going to represent our data using 3 different methods: using a pictograph, column graph, and a tally.
- Provide students with Appendix 2 so students can begin to put their information onto the graph.
- Provide students with Appendix 3 so students can begin to complete the graph.
- Provide Students with Appendix 4 so students can begin to complete the tally
- Once finished, reflect on the lesson. What was the lesson objectives? Can we give an answer to the question “which animal is the most common pet in the class?”
Appendix 1 – Students place a picture of the animal they have at home next to their name
|e.g Alex||(Insert picture of what pet they have)|
Appendix 2 – Get students to draw pictures of the number of animals for each category
Appendix 3 – Students colour the number squares for each person who has that pet
Appendix 4 – tally of the animals students have at home
Lesson 2 – Using digital systems to present data
- Ask students the following questions:
- ‘How could we use a computer to display our findings?’
- ‘What software/tools/devices would be best to use?’
- Explain that digital systems can help to:
- organise data
- display data creatively (help us share our data in a clear way)
- make meaning from data.
- Demonstrate how data can be displayed digitally.
- Model the creation of a bar graph, pie chart or digital picture graph/pictograph. If possible use an interactive whiteboard.
- This task could be undertaken with students working in pairs or small groups or could run as a whole-class activity, and will be dependent on resources and support available.
- Alternatively, students from higher year levels could be buddied with younger students to undertake this task.
- Students can present their data display to the class and provide an explanation of
- how they collected their data,
- why they chose to present it the way they did
- anything that they found surprising or unexpected about the data
- what they might do differently next time
