Lesson Title: Doubling and Halving Numbers up to 200

Learning Intention: By the end of the lesson, learners should be able to double and halve numbers up to 200.

Success Criteria: - Students can accurately double and halve numbers up to 200. - Students can explain the process of doubling and halving numbers.

Introduction: Begin the lesson by asking students if they know what it means to double a number. Discuss with the class what doubling means and give examples. Then, introduce the concept of halving a number and provide examples.

Main Part of the Lesson: 1. Share new knowledge: Teach students the strategies for doubling and halving numbers up to 200. Show them different methods, such as using a number line or mental math. 2. Stimulate discussion: Ask students to share their own strategies for doubling and halving numbers. Encourage them to explain their thinking to the class. 3. Activity: Provide students with a worksheet containing various numbers up to 200. Ask them to double or halve each number and write down their answers.

Plenary: Review the answers to the worksheet as a class. Discuss any common mistakes and clarify any misunderstandings. Ask students to explain their reasoning for their answers.

Differentiation: - For students who may struggle with the concept, provide manipulatives such as counters or number lines to help them visualize the process. - For students who grasp the concept quickly, challenge them to double and halve larger numbers or solve word problems involving doubling and halving.

Assessment Strategies: - Observe students during the activity to see if they are able to accurately double and halve numbers. - Use the completed worksheet to assess students’ understanding of the concept.

Higher Order Thinking Questions: 1. How can you use doubling and halving to solve multiplication and division problems? 2. Can you explain why doubling and halving are important strategies in mathematics? 3. How can you apply the concept of doubling and halving to real-life situations? (Analyzing)

By incorporating these elements into the lesson plan, students will have a comprehensive understanding of doubling and halving numbers up to 200.
