Unit 11 - Symmetry Around Us



Symmetry Around Us

General Learning Objectives
During the Lesson Subject-Specific Competencies
  • Recognize symmetry in nature, objects, and geometry.
  • Understand the concept of the line of symmetry and symmetrical figures.
  • Use mirrors and geometry tools to explore and create symmetrical designs.
  • Engage in physical movements that reflect symmetrical actions.
Learning Objectives After the Lesson
  • Identify and explain examples of symmetry in everyday life.
  • Create symmetrical designs using art and technology tools.
  • Collaborate effectively in team-based activities and improve coordination.
  • Understand the role of symmetry in the human body and motion.
Materials
  • Science/Observation: Pictures of symmetrical objects (e.g., butterflies, flowers, human faces).
  • Art and Technology: Paper, mirrors, markers, rulers, scissors, Mathigon Polypad web tool.
  • Physical Education: Open space for symmetry dance and games.
  • Art: Materials for T-shirt pattern designs (templates, markers, crayons).
  • Mathematics: Worksheets with symmetrical figures, geometry tools.

Activity 1: Exploring Symmetry (Science and Mathematics)

Objective: Introduce the concept of symmetry and identify symmetrical objects and figures. Introduction:
  • Show students pictures of symmetrical objects (e.g., flowers, butterflies, human faces).
  • Ask: “What do you notice about these objects? What happens if we fold them in half?”
  • Define symmetry and explain the concept of the line of symmetry.



Hands-On Activity:
  • Students use mirrors to explore symmetry in letters (e.g., A, B, F), shapes (e.g., rectangle, circle, triangle), and pictures.
  • Discuss why some objects have symmetry while others do not.
Worksheet Task:
  • Students complete exercises identifying symmetrical figures and drawing lines of symmetry.

Activity 2: Creating Symmetrical Designs (Technology and Engineering)

Objective: Use digital tools to create and explore symmetrical patterns. Task:
  • Students use the Mathigon Polypad web tool to create symmetrical patterns.
  • Explore how to reflect shapes along vertical, horizontal, and diagonal lines.
Reflection:
  • Discuss how symmetry is used in engineering and design (e.g., buildings, bridges, vehicles).

Activity 3: Symmetry Dance and Games (Physical Education)

Objective: Reinforce the concept of symmetry through movement and coordination. Symmetry Dance:
  • Students follow the teacher’s symmetrical movements (e.g., clapping, stomping).
  • Discuss: “If we draw a line down our bodies, are our movements symmetrical?"
Games:
  • Game 1: Mirror Movement – Students pair up and mirror each other’s movements.
  • Game 2: Symmetry Shapes – Students form symmetrical shapes with their bodies in groups.

  • Game 3. Rope pull -

Also known as Tug of War, or tugging war. It is an activity in which two teams compete against each other in a test of whole-body strength. It involves the use of a single piece of equipment, i.e., a rope. A clear mark is made in the middle of the rope, and on either side of the rope few meters away from the middle mark. At the start of the game central mark on the rope needs to be parallel to the central point on the ground. At a given mark, each team can start pulling the rope into their side. The objective of the game is for each team to pull the rope along with the members of the opposition team to their side. As soon as the central mark on the rope crosses over to the border line, the team to pull the rope to their area wins the game.

Activity 4: Art – Symmetrical Pattern Design

Objective: Create artistic designs demonstrating symmetry. Task:
  • Students create symmetrical patterns for a T-shirt design using markers and templates.
  • Encourage creativity with colors and shapes while ensuring symmetry.
Reflection:
  • Display designs and discuss the importance of symmetry in art and fashion.
Activity 5: Symmetry in the Human Body (Science and Mathematics) Objective: Explore symmetry in the human body and its role in motion. Discussion:
  • Talk about how the human body is symmetrical (e.g., left and right halves).
  • Discuss how symmetry aids movement and balance.
Interactive Task:
  • Students identify symmetrical motions (e.g., clapping, jumping) and asymmetrical ones (e.g., stepping).
Wrap-Up and Evaluation Class Discussion:
  • What did you learn about symmetry in nature, art, and your body?
  • How can you identify symmetry in everyday life?
Evaluation Criteria:
  • Creativity and accuracy in symmetrical designs.
  • Active participation in physical and group activities.
  • Completion of worksheets and use of digital tools.
Homework:
  • Students find three symmetrical objects at home and draw them, highlighting the line of symmetry.
  • Upload their drawings to Padlet for peer feedback.
STEPAM Components
