Grade 3 Mathematics Lesson Plan: Numbers Operation – Addition and Subtraction

Lesson Plan Title:
Grade 3 Mathematics Lesson Plan: Numbers Operation – Addition and Subtraction

Materials Needed:
– Whiteboard and markers
– Worksheets with addition and subtraction problems
– Number charts (1-100)
– Counters or small objects (e.g., beans, buttons) for practical exercises
– Projector or interactive whiteboard (if available)
– Maths textbooks (CAPS-aligned)

Learning Objectives:
By the end of the lesson, students should be able to:
1. Solve basic addition and subtraction problems within 100.
2. Understand and use the concepts of ‘borrowing’ and ‘carrying’ in subtraction and addition.
3. Apply addition and subtraction in word problems.
4. Demonstrate the ability to check their work for accuracy.

Vocabulary:
1. Addition – the process of calculating the total of two or more numbers.
2. Subtraction – the process of taking one number away from another.
3. Sum – the result of addition.
4. Difference – the result of subtraction.
5. Borrowing – a strategy used in subtraction when a larger digit is subtracted from a smaller one.

Previous Learning:
Students have previously learned to count, recognise, and write numbers up to 100. They have also worked with basic addition and subtraction facts up to 20.

Anticipated Challenges and Solutions:
– Challenge: Difficulty understanding the concept of borrowing and carrying.
Solution: Use visual aids and concrete objects to demonstrate the operations.
– Challenge: Errors in aligning numbers for vertical addition and subtraction.
Solution: Provide grid paper to help with number alignment.

Beginning Activities (4 minutes):
1. Greet the students and briefly review counting by tens to 100.
2. Introduce the lesson objectives and what students are expected to learn.
3. Quick warm-up: Ask students to solve a few simple addition and subtraction problems orally.

Middle Activities (32 minutes):
1. Direct Instruction (10 minutes):
– Demonstrate addition with carrying using a whiteboard and markers. Model a few examples, e.g., 38 + 27, explaining each step clearly.
– Demonstrate subtraction with borrowing using practical examples, e.g., 45 – 18. Use counters to visually show the borrowing process.

  1. Guided Practice (10 minutes):
  2. Hand out worksheets with addition and subtraction problems. Work through the first few problems together as a class.
  3. Circulate and assist students as they practice, ensuring they understand carrying and borrowing.
  4. Independent Practice (12 minutes):
  5. Allow students to complete the rest of the worksheet individually.
  6. Encourage students to check their work by reversing the operation (e.g., check addition with subtraction).

End Activities (4 minutes):
1. Collect the worksheets.
2. Exit Ticket: Ask each student to solve one addition and one subtraction problem on a piece of paper and hand it in as they leave.

Assessment and Checks for Understanding:
– Formative Assessment: Monitor student responses during guided practice and warm-up activities.
– Exit Tickets: Review to check for individual understanding.
– Worksheet Results: Evaluate completed worksheets to assess proficiency in addition and subtraction.

Differentiation Strategies for Diverse Learners:
– For struggling learners: Provide additional support with simpler problems and use concrete objects.
– For advanced learners: Offer more challenging problems, including multiple steps and larger numbers.
– Visual and kinesthetic learners: Incorporate visual aids and hands-on materials like counters.

Teaching Notes:
– Emphasise the importance of neatness in aligning numbers.
– Use relatable examples for word problems to engage students better.
– Encourage a supportive atmosphere where mistakes are seen as learning opportunities.

Accessibility Considerations:
– Ensure materials like worksheets and textbooks are available in an accessible format for learners with visual impairments.
– Adjust teaching methods and provide additional resources for learners with specific learning disabilities.

This lesson plan aligns with the CAPS curriculum expectations for Grade 3 Term 3 Mathematics, focusing on enhancing students’ proficiency in addition and subtraction within 100.
