Lesson 5 • How far we can jump

Use the How far can we jump PowerPoint to show students where they are in the statistical inquiry process.

Revise: We have a problem. We have a plan. We have data. We have analysed our data. Now we can make a conclusion about the investigation by answering our question.

Show students the class sticky note data display that was collected last lesson.

Review with students what they have noticed in the data, and some of their predictions from last session.

Pose the question: How far can students in our class jump?

Provide students with Our data story Student sheet. Ask students to use the sticky note data display to write a story with the data. Their story should answer the question “How far can students in our class jump?”. Explain that they should include evidence to support their noticings, inferences and predictions. They can represent the story of the data in any way they choose, so that it is clear to see the story.

Invite some students to share their story with the class.

Revise the PPDAC process in the How far can we jump PowerPoint. Review some of the challenges that arose at the different stages of the investigation process and how the students managed them.

Here it is important to normalise challenges as part of the process of statistical inquiry. The more students engage in statistical inquiry, the more they will recognise the patterns in the process. PPDAC has been introduced informally as a model to support students to engage in the inquiry process.
