**Subject:** Mathematics
**Grade Level:** Primary 6
**Topic:** Ratio and Proportion
**Duration:** 60 minutes
---
#### Objectives:
By the end of this lesson, students will be able to:
1. Understand the concept of ratio and how to represent it.
2. Simplify ratios.
3. Solve basic problems involving proportions.
#### Materials Needed:
- Whiteboard and markers
- Projector and slides
- Worksheets with practice problems
- Ruler
- Small objects for hands-on activities (e.g., blocks, beads)
- Chart paper and markers
#### Lesson Structure:
**Introduction (10 minutes):**
1. **Greeting and Warm-Up:**
- Start with a fun math-related riddle or question to engage the students.
2. **Objective Overview:**
- Explain the day's objectives and why understanding ratios and proportions is important in everyday life (e.g., cooking, dividing resources).
**Direct Instruction (20 minutes):**
1. **Introduction to Ratio:**
- Define a ratio and give simple examples (e.g., 3:1 for 3 apples to 1 orange).
- Show different ways to represent ratios (e.g., 3:1, 3 to 1, 3/1).
2. **Simplifying Ratios:**
- Demonstrate how to simplify ratios using the greatest common divisor.
- Work through examples as a class.
3. **Introduction to Proportion:**
- Define proportion as a statement that two ratios are equal.
- Explain cross-multiplication as a method to determine if two ratios are proportional.
- Provide several examples and solve them step by step.
**Guided Practice (15 minutes):**
1. **Simplifying Ratios:**
- Distribute worksheets with problems on simplifying ratios.
- Walk around to assist students as they work on their problems.
2. **Solving Proportions:**
- Have students work in pairs to solve proportion problems on the worksheets.
- Provide immediate feedback and support as they work.
**Hands-On Activity (10 minutes):**
1. **Interactive Ratio Activity:**
- Divide students into small groups.
- Provide each group with small objects (blocks, beads, etc.).
- Assign tasks involving the creation of ratios with the objects (e.g., 4 blue blocks to 2 red blocks should simplify to 2:1).
- Rotate around the classroom to observe and assist groups.
**Assessment and Review (5 minutes):**
1. **Quick Quiz:**
- Conduct a short, informal quiz with 3-4 questions on the whiteboard to assess understanding.
- Ask students to write their answers on mini whiteboards or paper.
- Review answers as a class and address any common mistakes.
**Conclusion (5 minutes):**
1. **Recap of the Lesson:**
- Go over the key points covered in the lesson.
2. **Real-Life Applications:**
- Discuss real-life scenarios where ratio and proportion are used.
3. **Assignment:**
- Assign a homework practice sheet with a mix of ratio and proportion problems to reinforce the day’s learning.
