**Lesson Plan: 2-D Shapes and Symmetry | Primary 2**
**Objective:**
Students will be able to recognize, name, and describe various 2-D shapes. They will also understand the basics of symmetry and identify lines of symmetry in different shapes.
**Materials:**
- Chart paper
- Markers/Crayons
- Scissors
- Pre-cut 2-D shapes (circle, triangle, square, rectangle, hexagon)
- Mirrors
- Symmetry worksheets
- Interactive whiteboard or projector
- Glue sticks
- Worksheets for shape recognition and symmetry activities
**Duration:**
60 minutes

**Lesson Structure:**
**I. Introduction (10 minutes)**
1. **Greeting and Warm-Up:**
Start with a short greeting and a fun song about shapes to capture students' attention and engage them.
2. **Objectives Overview:**
Briefly explain to the students that today they will be learning about different 2-D shapes and a special property called symmetry.
3. **Shape Review:**
Use chart paper or an interactive whiteboard to show and name basic 2-D shapes: circle, triangle, square, rectangle, and hexagon. Ask students if they recognize these shapes and where they might see them in everyday life.
---
**II. Direct Instruction (15 minutes)**
1. **Shape Characteristics:**
Review the characteristics (number of sides, vertices) of each shape one by one.
- **Circle:** No sides or vertices
- **Triangle:** 3 sides, 3 vertices
- **Square:** 4 equal sides, 4 vertices
- **Rectangle:** 4 sides (opposite sides equal), 4 vertices
- **Hexagon:** 6 sides, 6 vertices
2. **Symmetry Introduction:**
Introduce the concept of symmetry.
- Explain that a shape is symmetrical if it can be folded along a line to make two halves that match exactly.
- Show examples using pre-cut shapes and a mirror to demonstrate fold lines of symmetry. Emphasize that some shapes can have more than one line of symmetry.
---
**III. Guided Practice (15 minutes)**
1. **Shape Sorting Activity:**
- Divide students into small groups.
- Provide each group with a set of pre-cut shapes.
- Ask students to sort the shapes based on their characteristics and name each shape as they sort.
2. **Symmetry Exploration:**
- Distribute mirrors and symmetry worksheets.
- Instruct students to use the mirrors to find and draw lines of symmetry on the worksheet's shapes.
- Walk around the classroom to provide assistance and check for understanding.
---
**IV. Independent Practice (10 minutes)**
1. **Worksheet Activity:**
Provide a worksheet with multiple 2-D shapes where students will:
- Identify and label each shape.
- Draw the lines of symmetry where applicable.
- Color in the shapes.
---
**V. Assessment and Conclusion (10 minutes)**
1. **Class Discussion:**
- Review the completed worksheets as a class.
- Ask students to share which shapes have lines of symmetry and how many each has.
2. **Quick Quiz:**
- Give a short quiz to assess understanding, including identifying shapes and drawing lines of symmetry.
3. **Wrap-Up:**
- Summarize the key points of the lesson.
- Praise students for their participation and hard work.
4. **Homework Assignment:**
- Assign a simple homework task: students find and bring examples of symmetrical objects from home to share with the class in the next lesson.
---
**VI. Extension Activity:**
For early finishers or advanced students, provide an additional worksheet with more complex symmetrical patterns or introduce them to rotational symmetry.

This lesson plan ensures an interactive and comprehensive approach to learning about 2-D shapes and symmetry, engaging students with a mix of direct instruction, hands-on activities, and assessments to solidify their understanding.
