To captivate Year 10 students' interest in the properties, formulas, and applications of parallelograms.
Before entering the classroom, place a large envelope on each student’s desk, sealed and embossed with a question mark. As they enter, encourage them to take a seat quietly and to not open the envelopes just yet.
(5 minutes)
Start the lesson by projecting an image of a mysterious landscape featuring a lake, trees, and a large, beautifully designed parallelogram structure (like a pavilion or a bridge) in the foreground.
Ask the class: “What do you notice about this structure? What shapes can you identify?”
After a few responses, guide the discussion towards parallelograms.
(10 minutes)
Next, ask the students to open their envelopes. Inside, they’ll find a short note:
“Your detective skills are required! Our favourite math professor has designed a stunning new structure, but he misplaced some crucial measurements. Can you help solve the mystery of the missing parallelogram?”
(15 minutes)
Divide the class into small groups and assign each group a set of materials (graph paper, rulers, coloured pencils). Instruct them to work together to:
This engaging introduction aligns with the Australian Curriculum: Mathematics, specifically focusing on the understanding of geometric properties and reasoning, as well as developing teamwork and communication skills in solving mathematical problems.
Wrap up the introduction by bringing the class together to share their findings. Highlight how important parallelograms are in real-world applications like architecture, engineering, and design. This will set the stage for a deeper exploration of the topic throughout the lesson, ensuring students leave with both critical thinking and problem-solving skills.
