Distributive Law and Expanding Expressions
Students will apply the distributive law to expand algebraic expressions, including single term multiplication and basic binomial products.
Key Questions
- Explain how the distributive law simplifies expressions with parentheses.
- Analyze the difference between simplifying and expanding an expression.
- Construct an example where the distributive law is essential for solving a problem.
ACARA Content Descriptions
About This Topic
Digital Manipulation and Identity invites Year 9 students to critique the 'curated self' in the age of social media. By using digital tools like Photoshop or Procreate, students create hybrid portraits that blend their physical likeness with symbolic elements. This topic addresses the ACARA focus on using technologies to represent ideas and the exploration of identity through contemporary art practices.
Students learn that digital art is not just about filters; it is a sophisticated method of layering meaning. They investigate how distortion, colour grading, and compositing can reveal internal facets of personality that a traditional photograph cannot. This topic is most effective when students engage in collaborative problem-solving, helping each other navigate technical hurdles while discussing the ethical implications of digital 'perfection'.
Active Learning Ideas
Inquiry Circle: The Anatomy of a Selfie
Students work in pairs to deconstruct a popular social media image, identifying every 'manipulation' (lighting, angle, filter). They then discuss how these choices create a specific narrative about the person's identity.
Peer Teaching: Tool Mastery Stations
Students who are proficient in specific digital skills (e.g., masking, blending modes, liquify) act as 'experts' at different stations. Other students rotate through to learn one specific technique they can apply to their own hybrid portrait.
Think-Pair-Share: The Ethics of AI in Art
Provide students with a prompt about using AI-generated elements in their portraits. They must discuss whether an image is still 'theirs' if a computer generated parts of it, then share their stance with the class.
Watch Out for These Misconceptions
Common MisconceptionDigital art is 'cheating' because the computer does the work.
What to Teach Instead
The computer is a tool, like a brush. Students realise through hands-on practice that the artist must still make every decision regarding composition, lighting, and conceptual depth.
Common MisconceptionA portrait must look like the person to be successful.
What to Teach Instead
In contemporary art, a portrait can be symbolic or abstract. Peer feedback sessions help students value the 'story' or 'mood' of a digital work over mere physical accuracy.

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.
