# Digital Technology and Maths Activity – Data

Background
This activity is aimed at a grade 2 class and focuses on collecting and classifying data (ACMSP049), as well as representing and interpreting data (ACMSP050)

Lesson 1 – Data Collection

1. 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?’
2. 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?’
3. Create a record sheet/table for data collection
• create a record sheet similar to appendix 1
4. Once this data has been collected, students can begin to display that data.
5. 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.
6. Explain that we are going to represent our data using 3 different methods: using a pictograph, column graph, and a tally.
7. Provide students with Appendix 2 so students can begin to put their information onto the graph.
8. Provide students with Appendix 3 so students can begin to complete the graph.
9. Provide Students with Appendix 4 so students can begin to complete the tally
10. 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

 Name Animal 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

 Dog Cat Bird Goldfish Guinea Pig Horse

Appendix 3 – Students colour the number squares for each person who has that pet

 1 2 3 4 5 6 Dog Cat Guinea Pig Horse Bird Goldfish

Appendix 4 – tally of the animals students have at home

 Dog Cat Guinea Pig Horse Goldfish Bird Class Total

Lesson 2 – Using digital systems to present data

1. Ask students the following questions:
• ‘How could we use a computer to display our findings?’
• ‘What software/tools/devices would be best to use?’
2. 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.
3. 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.
4. 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.
5. Alternatively, students from higher year levels could be buddied with younger students to undertake this task.
6. 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
