Lesson Plan: Long Multiplication for Primary 3 Children

Subject: Mathematics Topic: Long Multiplication Grade Level: Primary 3 (8-9 years old)

Introduction: - Begin the lesson by asking the students if they know what multiplication is and if they have any prior knowledge of multiplication. - Explain that multiplication is a way of adding numbers together quickly and repeatedly. - Introduce the concept of long multiplication, which is used to multiply larger numbers.

Lesson Outline: 1. Warm-up Activity (5 minutes): - Display a multiplication table on the board and ask students to identify patterns or relationships they notice. - Have students practice skip counting by different numbers to reinforce the concept of multiplication.

- Introduction to Long Multiplication (10 minutes):
- Explain that long multiplication is used when multiplying larger numbers that cannot be easily multiplied mentally.
- Demonstrate the process of long multiplication using a two-digit number multiplied by a one-digit number.
- Model the steps of multiplying each digit of the two-digit number by the one-digit number and adding the results.

- Guided Practice (15 minutes):
- Provide students with a worksheet containing multiplication problems to solve using long multiplication.
- Circulate the classroom to provide assistance and guidance as needed.
- Encourage students to show their work neatly and step-by-step.

- Questioning (10 minutes):
- Engage students in a discussion by asking questions such as:
- Why do we use long multiplication instead of mental multiplication for larger numbers?
- What are the steps involved in long multiplication?
- Can you explain how you solved a particular problem on the worksheet?

- Engage students in a discussion by asking questions such as:
- Assessment (10 minutes):
- Distribute a short quiz or a set of word problems related to long multiplication.
- Assess studentsâ€™ understanding of the concept and their ability to apply it correctly.
- Provide feedback and address any misconceptions.

Differentiation: - For students who need additional support: - Provide manipulatives, such as base-ten blocks or counters, to help them visualize the multiplication process. - Offer simplified multiplication problems with smaller numbers. - Provide extra practice worksheets or online resources for reinforcement.

- For students who need extension:
- Assign more challenging multiplication problems involving larger numbers.
- Encourage them to explore different strategies for solving multiplication problems.
- Provide enrichment activities, such as creating their own multiplication word problems.

Plenary: - Summarize the main points of the lesson by reviewing the steps of long multiplication. - Ask students to share one thing they learned or found interesting about long multiplication. - Provide positive reinforcement and praise for their efforts.
