Quick summary: In this lesson, students will consider what they know about homelessness through a Colour–Symbol–Feeling thinking routine and then further develop their understanding of homelessness by watching ‘Emma’s Story‘ from the Life After The Oasis documentary. Students will then investigate homelessness statistics from different demographics in Australia including, Aboriginal and Torres Strait Islander peoples, youth, older persons and people with a disability. They will calculate the mean, median and frequencies, and describe the data using the shape of histograms they have created both individually and in small groups.
Life After The Oasis is a 75 minute documentary that explores the issues, interventions and mindsets associated with youth homelessness in Australia. The film revisits characters and stories from the original 2008 documentary The Oasis and how opportunities and experiences have shaped their lives over the last ten years. Find out how to screen or view the film here.
Warning: The documentary and the clips contained in this lesson, contains explicit language, images of drug use and confronting scenes and may upset some viewers. Teachers should use their personal discretion when showing the documentary. This resource deals with the rising problem of youth homelessness and its associated social and personal issues. There may be students in your class who have experienced some of the issues discussed. You are encouraged to arrive at a set of agreements and ground rules for discussion with your class about the best way to approach the issues being covered in a way that recognises the dignity of our fellow classmates.

- Students will be able to determine population means and medians.
- Students will be able to compare means, medians and ranges of two sets of numerical data which have been displayed using histograms.
- Students will understand how statistics and data are one way of highlighting and understanding the complexities of a social issue such as homelessness.
21st century skills: Communicating
Australian Curriculum Mapping
Years 9 Mathematics:
- Construct back-to-back stem-and-leaf plots and histograms and describe data, using terms including ‘skewed’, ‘symmetric’ and ‘bi modal’ (ACMSP282) (Stem-and-leaf plots not included in this lesson)
- Compare data displays using mean, median and range to describe and interpret numerical data sets in terms of location (centre) and spread (ACMSP283)
