Combining Like Terms
Students will combine like terms and apply the order of operations to simplify algebraic expressions, focusing on efficiency and accuracy.
Key Questions
- Justify why only 'like terms' can be combined in an algebraic expression.
- Evaluate the impact of incorrect order of operations on simplifying expressions.
- Compare the efficiency of different methods for simplifying complex expressions.

About This Topic
Urban Interventions and Street Art explores the intersection of art, geography, and social ethics. Students investigate how public spaces can be transformed into galleries that challenge authority, celebrate identity, or highlight local issues. This topic is particularly relevant in the Australian context, where street art in cities like Melbourne and Brisbane has become a significant part of the cultural fabric, often featuring voices from marginalised communities and First Nations perspectives.
Students examine the difference between vandalism and intentional public art, considering the role of the 'site' in the meaning of the work. This topic comes alive when students can physically model the patterns of urban movement and debate the ethics of public ownership. Active learning allows them to step into the roles of city planners, artists, and residents to understand the complex power dynamics at play.
Active Learning Ideas
Formal Debate: Vandalism vs. Vitality
Divide the class into 'City Council Members' and 'Street Artists'. They must debate a proposal for a new legal graffiti wall in a heritage-listed area, using arguments about community identity, property rights, and tourism.
Inquiry Circle: Site-Specific Mapping
In small groups, students use a map of the school or local suburb to identify 'dead zones' that could benefit from an intervention. They must photograph the site and sketch a digital overlay of a proposed artwork that responds to that specific location's history.
Role Play: The Artist's Pitch
Students act as artists pitching a public mural concept to a 'Community Board' (their peers). The pitch must explain how the symbols used represent the local multicultural community or First Nations history of the land.
Watch Out for These Misconceptions
Common MisconceptionAll street art is illegal graffiti.
What to Teach Instead
Many street art projects are commissioned or sanctioned by councils to prevent tagging and build community pride. Using a 'sorting' activity with images of different public works helps students distinguish between styles and legalities.
Common MisconceptionStreet art is just about the image.
What to Teach Instead
The location (the 'site') is often as important as the art itself. Peer discussions about why a stencil was placed on a specific bin or bridge help students understand the importance of context in public art.

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.
