**Grade Level:** Junior Secondary 1
**Duration:** 60 minutes
**Curricular Area:** Mathematics
**Materials Needed:**
- Whiteboard and markers
- Projector / Computer (for visuals or videos)
- Graph paper
- Rulers
- Colored pencils
- Sample data sets (printed handouts)
- Access to interactive statistical tools or software (optional)
**Learning Objectives:**
By the end of this lesson, students will be able to:
1. Understand basic concepts of data and statistics.
2. Identify various types of data representations: bar graphs, line graphs, pie charts, and histograms.
3. Create and interpret different types of graphs from given data.
4. Discuss the importance of accurate data representation.

**Lesson Outline:**
**Introduction (10 mins):**
1. **Warm-Up Activity:**
- Begin with a quick review of what data and statistics are. Ask students to list examples of where they’ve encountered data in everyday life (e.g., weather reports, sports scores, school grades).
2. **Learning Objectives Overview:**
- Present the day's learning objectives on the board and discuss what students will learn and do during the lesson.
**Instruction (15 mins):**
1. **Definition and Purpose:**
- Explain the purpose of statistical data representation (to communicate information clearly and efficiently).
2. **Types of Data Representations:**
- Use the projector to show examples of bar graphs, line graphs, pie charts, and histograms.
- Briefly explain when and why each type of graph is used (e.g., bar graphs for categorical data, line graphs for trends over time, pie charts for parts of a whole, histograms for data distribution).
**Guided Practice (15 mins):**
1. **Creating Graphs:**
- Hand out sample data sets to students.
- Walk through an example of creating a bar graph using the data. Show step-by-step how to draw the axes, label them, and plot the data points.
- Repeat with a line graph using a different sample data set.
2. **Class Activity:**
- Divide students into small groups and assign each group a different type of graph to create using provided data sets. Distribute graph paper, rulers, and colored pencils.
**Independent Practice (15 mins):**
1. **Group Presentations:**
- Have each group present their graph to the class, explaining how they constructed it and what information it represents.
- Encourage other students to ask questions and provide constructive feedback.
**Discussion and Reflection (5 mins):**
1. **Why Accurate Data Representation Matters:**
- Facilitate a discussion on the importance of accurate data representation and how misleading graphs can affect decision-making.
- Share real-life consequences of inaccurate data representation (e.g., in medicine, finance, or elections).
**Conclusion and Assessment (5 mins):**
1. **Quick Quiz:**
- Give a short quiz where students match types of graphs to the appropriate data sets or scenarios.
2. **Homework Assignment:**
- Assign a task for students to find a graph from a newspaper, magazine, or online source and bring it to the next class for discussion. They will need to identify the graph type, summarize the data it represents, and comment on its accuracy and clarity.
**Extension Activities: (Optional)**
- Create digital graphs using online tools or software.
- Explore more complex statistical representations, such as scatter plots and box plots, for advanced learners.
**Assessment Criteria:**
- Ability to accurately interpret and create various types of graphs.
- Participation in group work and discussions.
- Performance in the quick quiz and quality of the homework assignment.
