### 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.
