Year 3 Mathematics Lesson Plan: Adding Two-Digit Numbers

Lesson Duration: 30 minutes

Learning Objectives

• Students will understand the concept of adding two-digit numbers.
• Students will practice addition with and without regrouping.
• Students will develop confidence in solving addition problems.

Materials Needed

• Whiteboard and markers
• Worksheets with addition problems
• Counters or base-ten blocks (optional)
• Pencils and erasers

Introduction (5 minutes)

1. Engage the Students:

   • Start the lesson by asking students if they have ever added two numbers together. Discuss their experiences briefly.
   • Write a simple two-digit addition problem on the board, for example, 23 + 15.

2. Explain the Concept:

   • Discuss the concept of place value (tens and units) and how it applies to addition.
   • Break down the addition problem using the place value method:
     • Add the tens (2 + 1 = 3)
     • Add the units (3 + 5 = 8)
     • Combine the results (38).

Direct Instruction (10 minutes)

1. Demonstrate with Examples:

   • Solve a few more examples on the board, ensuring to include both with and without regrouping:
     • Example 1:
       • 27 + 34
       • Break down:
         • Tens: 2 + 3 = 5
         • Units: 7 + 4 = 11 (regroup to 1 ten and 1 unit)
         • Final result: 61.
     • Example 2:
       • 45 + 26
       • Tens: 4 + 2 = 6
       • Units: 5 + 6 = 11 (regroup to 1 ten and 1 unit)
       • Final result: 71.

2. Class Practice:

   • Have students work together in pairs to solve a addition problems on the board. Walk around to offer support and ensure understanding.

Guided Practice (10 minutes)

1. Worksheet Activity:

   • Distribute worksheets containing a mix of two-digit addition problems, some requiring regrouping and some not. Examples of problems to include:

     • 57 + 24
     • 63 + 19
     • 38 + 44
     • 76 + 59

   • Allow students to work independently, but encourage them to discuss their processes with a partner.

Conclusion (5 minutes)

1. Review and Reflect:
   • Ask students to share their answers and the methods they used to solve a few problems.
   • Address any common misconceptions or difficulties encountered during the lesson.
   • Reinforce the importance of checking work, especially with regrouping.

Homework Assignment

• Complete the following addition problems. Students should show their work.

Homework Problems:

1. 32 + 15 = ?
2. 41 + 29 = ?
3. 58 + 34 = ?
4. 25 + 37 = ?
5. 44 + 19 = ?

Correct Answers to Homework

1. 32 + 15 = 47
2. 41 + 29 = 70
3. 58 + 34 = 92
4. 25 + 37 = 62
5. 44 + 19 = 63
