Lesson Plan for Primary 4 - Mathematics - ivision Of 2-digit And 3-digit Numbers By Numbers

### Mathematics Lesson Plan: Division of 2-Digit and 3-Digit Numbers by Numbers Up to 9 Without Remainder **Grade Level:** Primary 4 **Subject:** Mathematics **Topic:** Division of 2-digit and 3-digit numbers by numbers up to 9 without remainder **Duration:** 60 minutes **Objectives:** 1. Students will be able to divide 2-digit and 3-digit numbers by single-digit numbers up to 9 without any remainder. 2. Students will develop an understanding of the division process. 3. Students will be able to solve word problems that involve division. **Materials Needed:** - Whiteboard and markers - Division flashcards - Practice worksheets - Number line (optional) - Counters or blocks for hands-on practice - Chart paper and markers - Pencils and erasers **Introduction (10 minutes):** 1. **Greeting and Warm-Up:** - Start by greeting the students and quickly reviewing previous knowledge about multiplication and sharing equally. 2. **Introduction to Division:** - Explain that today's topic is learning how to divide bigger numbers by smaller numbers without any remainder. Use simple real-life examples, such as sharing 12 apples among 3 friends. **Direct Instruction (20 minutes):** 1. **Explaining Division:** - Use the whiteboard to demonstrate a simple division problem like 24 ÷ 4. - Write down the division problem and explain each step: 1. Divide the first digit. 2. Multiply and subtract. 3. Bring down the next digit and repeat. 2. **Concept of No Remainder:** - Emphasize that the division we are focusing on has no remainder, meaning the number divides evenly. - Show how to handle 3-digit examples like 135 ÷ 5. **Interactive Practice (15 minutes):** 1. **Guided Practice:** - Solve a few division problems together as a class using the whiteboard. Examples can be: - 42 ÷ 7 - 84 ÷ 6 - 144 ÷ 9 2. **Group Activity:** - Divide the class into small groups and provide each group with division flashcards. - Each group works together to solve the problems, using counters and blocks if necessary to visualize the division process. **Independent Practice (10 minutes):** 1. **Worksheet Completion:** - Hand out practice worksheets with a mix of 2-digit and 3-digit division problems. - Students solve the problems independently to reinforce their understanding. **Application (10 minutes):** 1. **Word Problems:** - Provide a few word problems related to real-life scenarios. For example: - "A farmer has 72 apples and needs to put them equally into 9 baskets. How many apples will each basket have?" - Discuss and solve these problems together, highlighting how to identify the division operation in a word problem. **Closing (5 minutes):** 1. **Review:** - Recap the key points of the lesson: the process of division, handling 2-digit and 3-digit numbers, and ensuring there is no remainder. 2. **Q&A:** - Open the floor for any questions from students, clarifying any doubts they may have. 3. **Homework Assignment:** - Assign a few division problems for homework to reinforce the day's lesson. **Assessment:** - Monitor students during group activities and independent practice. - Collect and review worksheets to assess understanding. - Observe participation and accuracy during word problem discussions. **Extensions:** - For advanced students, introduce simple problems involving remainders or larger numbers. - For students needing more practice, provide additional worksheets or one-on-one assistance. **Reflection:** - At the end of the lesson, jot down what worked well and what could be improved in future lessons. --- This lesson plan outlines a structured approach to teaching division, ensuring students grasp the concept through various learning activities and reinforcing their skills with practice.
