Lesson Plan: Shape, Position and Movement - Exploring Triangles

Subject: Mathematics

Level: First Level

Topic: Shape, Position and Movement - Exploring Triangles

Desired Outcome: I can explore and discuss how and why different shapes fit together and create a tiling pattern with them.

Learning Objectives:

• To identify and name different types of triangles.
• To explore the properties of triangles.
• To create a tiling pattern using triangles.
• To discuss how and why different shapes fit together.

Assessment Criteria:

• Students can identify and name different types of triangles.
• Students can explain the properties of triangles.
• Students can create a tiling pattern using triangles.
• Students can discuss how and why different shapes fit together.

Resources:

• Triangles cut out of paper or card.
• Whiteboard and markers.
• Worksheets for students to complete.

Introduction (10 minutes):

• Begin the lesson by asking students if they know what a triangle is.
• Show them different types of triangles (equilateral, isosceles, scalene) and ask them to identify and name them.
• Discuss the properties of triangles (three sides, three angles, sum of angles is 180 degrees).

Main Activity (30 minutes):

• Give each student a set of triangles cut out of paper or card.
• Ask them to explore the different types of triangles and their properties.
• Encourage them to create different shapes and patterns using the triangles.
• Once they have created a few shapes, ask them to create a tiling pattern using the triangles.
• Discuss with the class how and why different shapes fit together to create a tiling pattern.

Plenary (10 minutes):

• Ask students to share their tiling patterns with the class.
• Discuss the different shapes and patterns that were created.
• Ask students to explain how and why different shapes fit together to create a tiling pattern.

Assessment (10 minutes):

• Distribute worksheets to students to complete.
• The worksheet should include questions about identifying and naming different types of triangles, explaining the properties of triangles, creating a tiling pattern using triangles, and discussing how and why different shapes fit together.
• Collect the worksheets and assess them according to the assessment criteria.

Extension Activity:

• For students who finish early, ask them to create a tiling pattern using different shapes (not just triangles).
• Encourage them to explore the properties of different shapes and how they fit together to create a pattern.
