Lesson Plan: Solving Real-Life Problems Using Thermometers and Temperature

Grade Level: Primary Year 4 Subject: Mathematics

Lesson Objectives: 1. Students will be able to read and interpret temperatures on a thermometer. 2. Students will be able to solve real-life problems involving temperature. 3. Students will be able to apply critical thinking skills to analyze and solve temperature-related problems. 4. Students will be able to differentiate between different temperature scales (Celsius and Fahrenheit).

Materials: - Thermometers (at least one per group) - Real-life temperature-related problems (e.g., weather forecasts, cooking temperatures) - Worksheets (links provided below) - Whiteboard or chart paper - Markers - Pencils

Lesson Procedure:

1. Lesson Starter (Visible Thinking Routine):
   • Display a picture of a thermometer on the whiteboard or chart paper.
   • Ask the students: “What do you think this tool is used for? How does it work?”
   • Allow students to share their thoughts and ideas.
   • Write down their responses on the board.
   • Explain that today’s lesson will focus on using thermometers to solve real-life problems related to temperature.
2. Introduction to Thermometers and Temperature (VTR):
   • Show a real thermometer to the students and explain its parts (bulb, stem, scale).
   • Discuss the concept of temperature and its measurement using thermometers.
   • Introduce the two most commonly used temperature scales: Celsius and Fahrenheit.
   • Use a VTR (Visible Thinking Routine) such as “See-Think-Wonder” to encourage students to observe the thermometer and share their thoughts and questions about it.
3. Group Task: Reading and Interpreting Temperatures:
   • Divide the students into small groups (3-4 students per group).
   • Provide each group with a thermometer and a set of temperature-related problems.
   • Instruct the students to work together to read and interpret the temperatures on the thermometer and solve the given problems.
   • Circulate among the groups to provide guidance and support as needed.
   • Encourage students to discuss their strategies and reasoning with their group members.
4. Critical Thinking Question:
   • After the groups have had sufficient time to work on the task, gather the whole class together.
   • Pose a critical thinking question related to temperature, such as: “Why is it important to measure and monitor temperature in different situations?”
   • Allow students to share their thoughts and engage in a class discussion.
   • Encourage students to think about the practical applications of temperature measurement in various contexts.
5. Challenge Question:
   • Present a challenge question to the students, such as: “Can you think of a situation where knowing the temperature is crucial for safety or well-being?”
   • Give students a few minutes to think individually, and then ask them to share their responses with a partner.
   • Select a few pairs to share their answers with the whole class.
   • Discuss the importance of temperature awareness in different scenarios, such as extreme weather conditions or food preparation.
6. Differentiation:
   • Provide additional support to struggling students by pairing them with a more confident peer during the group task.
   • For advanced students, encourage them to explore temperature conversions between Celsius and Fahrenheit and challenge them with more complex temperature-related problems.
7. Plenary:
   • Summarize the key concepts covered in the lesson, emphasizing the importance of temperature measurement in real-life situations.
   • Allow students to ask any remaining questions or share any insights they gained during the lesson.
   • Provide feedback and praise for their efforts and participation.
8. Worksheets:
   • Distribute worksheets to the students to reinforce their understanding of temperature and thermometers.
   • Here are some links to worksheets that can be used:

     • Worksheet 2: [Link]
     • Worksheet 3: [Link]

Note: The worksheets can be adapted based on the specific needs and curriculum requirements of your school or region.

Assessment: - Observe students’ participation and engagement during the group task and class discussions. - Review completed worksheets to assess students’ understanding of temperature measurement and problem-solving skills. - Provide feedback and support as needed.

Extension Activities: - Encourage students to conduct temperature experiments at home or in the school environment, such as measuring the temperature of different objects or locations. - Explore online resources or educational apps that provide interactive temperature-related activities and games.
