Lesson Plan: Shape, Position, and Movement - Symmetry in Shapes

Subject: Mathematics Topic: Shape, Position, and Movement - Symmetry in Shapes Level: First Level (Primary 1-3) Curriculum: Scottish Curriculum for Excellence

Desired Outcome: I have explored symmetry in my own and the wider environment and can create and recognize symmetrical pictures, patterns, and shapes.

Learning Objectives: 1. Identify and describe symmetrical shapes in the environment. 2. Create symmetrical pictures, patterns, and shapes. 3. Recognize and complete symmetrical patterns and shapes.

Assessment: 1. Observation during class discussions and activities. 2. Completion of symmetrical pictures and patterns. 3. Participation in group activities and discussions.

Resources: 1. Chart paper and markers 2. Symmetrical shapes flashcards 3. Construction paper 4. Scissors 5. Glue 6. Worksheets with symmetrical patterns and shapes

Lesson Duration: 60 minutes

Procedure:

Introduction (10 minutes): 1. Begin the lesson by asking students if they know what symmetry means. 2. Discuss symmetry as a concept of balance and similarity in shapes. 3. Show examples of symmetrical shapes in the classroom or on the chart paper. 4. Ask students to identify the symmetrical parts of the shapes.

Development (30 minutes): 1. Introduce the concept of line symmetry and explain that a shape has line symmetry if it can be divided into two equal parts that are mirror images of each other. 2. Show various symmetrical shapes using flashcards and ask students to identify the line of symmetry. 3. Engage students in a discussion about symmetrical shapes they have seen in their environment (e.g., buildings, nature, objects). 4. Provide students with construction paper, scissors, and glue. 5. Instruct them to create their own symmetrical shapes by folding the paper and cutting along the fold line. 6. Encourage students to explore different shapes and patterns. 7. Allow time for students to share and discuss their creations with their peers.

Practice (15 minutes): 1. Distribute worksheets with symmetrical patterns and shapes. 2. Instruct students to complete the missing half of each pattern or shape to make it symmetrical. 3. Circulate the classroom to provide assistance and monitor progress. 4. After completion, review the worksheets together as a class, discussing the symmetrical elements.

Conclusion (5 minutes): 1. Recap the lesson by asking students to share what they have learned about symmetry in shapes. 2. Discuss how symmetry is present in our everyday lives and the importance of recognizing and appreciating it. 3. Encourage students to continue exploring symmetry in their environment and creating symmetrical shapes and patterns.

Extension Activity (optional): 1. Provide students with a variety of magazines or newspapers. 2. Instruct them to cut out pictures of symmetrical objects or shapes and create a collage. 3. Display the collages in the classroom or school hallway to showcase students’ understanding of symmetry.

Note: Adapt the lesson plan and activities according to the specific needs and abilities of your students.
