Measures of Central Tendency: Mean, Median, Mode
Students will calculate and compare the mean, median, and mode of various data sets.
Key Questions
- Explain which measure of center best represents a data set with extreme outliers.
- Differentiate between the mean, median, and mode in terms of their calculation and interpretation.
- Analyze how adding a new data point affects the mean, median, and mode of a set.
ACARA Content Descriptions
About This Topic
The Art of Selection introduces Year 8 students to the role of the curator. It's about developing the critical 'eye' needed to choose works that tell a cohesive story. This topic aligns with ACARA's focus on evaluating and reflecting on artworks, as well as understanding how exhibitions are shaped by specific themes or narratives. Students learn that what is *left out* of a gallery is often as important as what is included.
In the Australian context, this might involve curating a 'virtual' exhibition of local artists that reflects a theme like 'Identity' or 'Our Environment'. This topic moves students from being 'makers' to being 'critics' and 'organizers'. It is best taught through collaborative sorting activities and 'pitching' sessions, where students must justify their selections based on aesthetic and thematic criteria.
Active Learning Ideas
Inquiry Circle: The Theme Sort
Groups are given a 'deck' of 20 diverse artworks and three different 'Exhibition Themes' (e.g., 'Conflict', 'Nature', 'The Future'). They must select only 5 works for one theme and justify why those 5 create the strongest narrative together.
Simulation Game: The Gallery Boardroom
Students act as a 'Gallery Committee'. They are presented with two 'finalists' for a prestigious exhibition spot. They must debate the merits of each work based on a set of criteria (e.g., 'Does it represent our community?') and vote on the winner.
Think-Pair-Share: The 'Odd One Out'
Show a collection of four images where one doesn't quite fit the theme. Students identify the 'odd one out' with a partner and discuss how its presence changes the 'message' of the other three.
Watch Out for These Misconceptions
Common MisconceptionCurating is just picking your 'favorite' paintings.
What to Teach Instead
Curating is about 'thematic fit' and 'narrative'. A curator might choose a work they don't personally like because it's essential for the story the exhibition is telling.
Common MisconceptionAll art in a gallery is 'good'.
What to Teach Instead
Art is selected based on a variety of factors, including historical importance, social relevance, and even funding. Understanding this helps students become more critical viewers of art institutions.

Planning templates for Mathematics
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
unit plannerMath Unit
Plan a multi-week math unit with conceptual coherence: from building number sense and procedural fluency to applying skills in context and developing mathematical reasoning across a connected sequence of lessons.
rubricMath Rubric
Build a math rubric that assesses problem-solving, mathematical reasoning, and communication alongside procedural accuracy, giving students feedback on how they think, not just whether they got the right answer.
