Lesson plan for Grade 3 according to CAPS documents
Subject: Mathematics
Grade: 3
Topic: Addition and Subtraction with Regrouping
Duration: 45 minutes
Learning Objectives:
By the end of the lesson, students will be able to:
- Understand the concept of regrouping in addition and subtraction
- Add and subtract two or three digit numbers with regrouping
- Apply regrouping to solve word problems
Resources:
- Whiteboard and markers
- Worksheets for practice

Introduction (5 minutes):
- Begin the lesson by revising the concept of addition and subtraction with carrying and borrowing.
- Define regrouping as the process of moving values from one place value to another in order to solve addition and subtraction problems.
- Engage students in a brief discussion about why regrouping is necessary when adding or subtracting numbers.
Body of the Lesson (30 minutes):
- Demonstrate the process of regrouping in both addition and subtraction using visual aids and examples on the whiteboard.
- Allow students to practice regrouping with two-digit numbers on their own or in pairs using counters or manipulatives.
- Once students have mastered regrouping with two-digit numbers, introduce three-digit numbers and repeat the process.
Guided Practice (10 minutes):
- Give students worksheets to complete with various addition and subtraction problems that require regrouping.
- Walk around the classroom to check for understanding and offer assistance where necessary.
- Encourage students to explain their thinking and justify their answers.
Conclusion (5 minutes):
- Have students share and discuss their answers to the worksheets as a class.
- Summarize the key points of the lesson on regrouping in addition and subtraction.
- Assign additional practice or homework to reinforce the concept of regrouping.
Assessment:
- Assess students' understanding of regrouping through their completion of the worksheets and their ability to explain their problem-solving strategies.
- Use informal observation and questioning during the lesson to gauge individual student understanding.
