Lesson Plan Title:
Grade 3 Mathematics Lesson Plan: Introduction to Long Division
Materials Needed:
– Whiteboard and markers
– Long division worksheets
– Counters or manipulatives
– Posters showing the steps of long division
– Lined paper and pencils
– Interactive whiteboard or projector
Learning Objectives:
– Understand the concept of division and its relation to multiplication.
– Learn and apply the steps of long division to solve problems with dividends up to three digits and divisors of one digit.
– Develop skills to check the accuracy of their division by multiplication.
Vocabulary:
1. Dividend – The number being divided in a division problem.
2. Divisor – The number by which another number (the dividend) is divided.
3. Quotient – The result of division.
4. Remainder – The amount left over after division when the dividend is not evenly divisible by the divisor.
5. Long Division – A method of solving division problems involving multiple digits.
Previous Learning:
Students have learned basic division facts, where they divided smaller numbers and understood division as splitting or sharing equally. They have also mastered multiplication tables up to 10, which will help in this lesson.
Anticipated Challenges and Solutions:
– Challenge: Understanding the multi-step process of long division.
– Solution: Break down the process into smaller, manageable steps and use visual aids.
– Challenge: Keeping track of place values.
– Solution: Use lined paper to organise calculations clearly and ensure alignment.
– Challenge: Making mistakes with subtraction during division.
– Solution: Incorporate extra practice and have peer reviews.
Beginning Activities (4 minutes):
1. Introduction (2 min): Briefly explain the learning objectives and connect the lesson to their prior knowledge of division.
2. Activation of Prior Knowledge (2 min): Ask students to solve a few simple division problems and discuss how they relate to multiplication. Write one simple problem on the whiteboard and have students solve it using counters if necessary.
Middle Activities (32 minutes):
- Direct Instruction (10 min):
- Explain the steps of long division using a simple example (e.g., 48 รท 4).
- Demonstrate each step visually on the whiteboard and correspond with the steps on the poster.
- Break it down: Divide, Multiply, Subtract, Bring Down, Repeat.
- Guided Practice (12 min):
- Work through several long division problems together as a class.
- Have students come to the board to participate, ensuring broad engagement.
- Use manipulatives to represent the division process physically.
- Independent Practice (10 min):
- Provide worksheets with a mix of simple and moderately challenging long division problems.
- Encourage students to check their answers with multiplication.
- Walk around to offer individual support.
End Activities (4 minutes):
1. Exit Ticket (4 min):
– Ask students to solve one division problem independently on a small piece of paper and hand it in as they leave.
– Ensure to include space for students to show their work, so you can see their process.
Assessment and Checks for Understanding:
– Observe students during guided practice.
– Collect and review the independent practice worksheets.
– Use the exit ticket to quickly assess individual understanding.
Differentiation Strategies for Diverse Learners:
– For Struggling Learners: Provide additional manipulatives, one-on-one support, or simplified problems focusing on smaller numbers.
– For Advanced Learners: Offer more challenging problems with larger dividends or introduce remainders in division.
– Group Work: Pair students for peer tutoring, where stronger students help those who struggle.
Teaching Notes:
– Highlight the importance of understanding each step rather than rush through to get the answer.
– Reinforce the relationship between division and multiplication throughout the lesson.
– Accessibility: Use large visual aids and ensure that digital resources are compatible with screen readers.
As students are still consolidating basic division concepts, patience and consistent reinforcement will be key throughout this lesson. Encourage questions and celebrate small victories to build their confidence in this new skill.
