Perimeter of Polygons
Students will calculate the perimeter of various polygons, including composite shapes.
Key Questions
- Differentiate between perimeter and area in terms of what they measure.
- Design a method to find the perimeter of an irregular polygon.
- Analyze how changes in side lengths affect the perimeter of a shape.

About This Topic
Choreographing a Narrative challenges Year 7 students to use movement to tell a story or explore a theme. This topic brings together the BASTE elements and cultural understandings to create original works. In the Australian Curriculum, students are encouraged to use dance to communicate ideas and emotions to an audience. They learn that a 'narrative' doesn't have to be a literal plot; it can be an abstract exploration of a concept like 'growth,' 'conflict,' or 'connection to place.'
Students focus on the structure of a dance, the beginning, middle, and end, and the importance of transitions. This unit develops critical thinking and collaborative skills as students must negotiate and refine their ideas within a group. This topic is best taught through iterative, student-centered workshops where students 'draft' movements, receive peer feedback, and refine their choreography in a supportive environment.
Active Learning Ideas
Inquiry Circle: The Prop Prompt
Groups are given a simple prop (e.g., a length of blue fabric or a single chair). They must choreograph a 1-minute piece where the prop represents something else (e.g., a river, a barrier, a memory) to tell a short story.
Peer Teaching: Transition Swap
Two groups each create two 'main' movements. They then swap groups, and the new group must choreograph the 'transition' that connects those two movements smoothly, focusing on flow and timing.
Think-Pair-Share: Abstracting an Idea
Students choose a word (e.g., 'friendship'). They think of a literal action for it (a handshake), then work with a partner to 'abstract' it by changing the level, speed, or energy until it becomes a dance move.
Watch Out for These Misconceptions
Common MisconceptionA dance story has to have characters and a clear plot like a movie.
What to Teach Instead
Dance often uses 'thematic' narrative. Active exercises in 'abstracting' everyday movements help students see that they can communicate a feeling or an idea without a literal storyline.
Common MisconceptionThe best dances are the ones with the most difficult tricks.
What to Teach Instead
A simple movement performed with clear intention and good transitions is often more effective. Peer feedback sessions help students focus on 'clarity of message' rather than just technical difficulty.

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.
