Resources

• Geometry handout (Definitions and key concepts)
• Whiteboard and markers
• Set of geometrical shape manipulatives for each group
• Worksheets for individual activities
• Projector and computer for presentations

Lesson Structure

Introduction (10 minutes)

• Greeting and Setting Expectations: Quickly outline the objectives and expectations for today's session.
• Engagement Activity: Pose a quick challenge where students guess the shape being described based on its properties (e.g., "I have three sides and three angles, what am I?").

Main Activities (25 minutes)

1. Exploring Shapes and Definitions (10 minutes)

• Group Activity: Students work in groups of 4. Each group receives a set of shape manipulatives and a matching activity sheet. They must match shapes to the correct names and properties.
• Discussion: Regroup and discuss findings. Highlight the unique properties of each shape and address any misconceptions.

2. Property Match (10 minutes)

• Individual Task: Using the handouts, students complete a worksheet where they link shapes to their properties (e.g., number of sides, angles, symmetry).
• Interactive Review: Use the projector to show answers, allowing students to correct and discuss their worksheets in real-time.

3. Shape Creation Challenge (5 minutes)

• Creative Application: Challenge students to use their manipulatives to form a new shape by combining two or three different shapes. Discuss as a class the properties of the newly created shapes.

Conclusion (5 minutes)

• Summary: Recap the session, emphasizing the key points about geometric shapes and their properties.
• Exit Ticket: Hand out a quick quiz with three questions covering the day’s material to gauge understanding and retention.
• Homework Assignment: Students are to draw their favorite room at home and label the shapes they see (e.g., rectangular door, circular clock).

Assessment

• Observation during group activities to assess understanding and participation.
• Review of worksheets and exit tickets to ensure objectives were met.
• Homework assignment to apply learning to real-world context.

This lesson plan provides a structured approach to introducing geometry and shapes, promoting engagement through interactive and hands-on activities, suitable for diverse learning levels within the New Zealand Curriculum framework for mathematics.
