Lesson Outline
Introduction (5 minutes)
- Start the lesson by asking the students, "What do we do when we add things together?"
- Briefly explain that addition is like putting two groups of objects together to find out how many there are in total.
Direct Instruction (10 minutes)
- Use counting blocks to demonstrate addition visually.
- Show 2 blocks and 3 blocks.
- Count them together: "Let’s count: 1, 2, 3, 4, 5. We have 5 blocks in total!"
- Introduce the addition equation: "2 + 3 = 5". Write this on the whiteboard.
- Show different addition facts using flashcards. Example: 1 + 4, 2 + 2, and 3 + 1.
Guided Practice (5 minutes)
- Hand out counting blocks and encourage students to work in pairs to create their own addition problems with the blocks provided.
- Ask them to represent their problems on the whiteboard, drawing the objects or writing the number sentences.
Independent Practice (5 minutes)
- Distribute a worksheet with simple addition problems (examples below) for students to complete individually:
- 1 + 1 = ___
- 2 + 3 = ___
- 4 + 1 = ___
- 0 + 5 = ___
Conclusion (5 minutes)
- Review the addition problems from the worksheet as a class.
- Highlight different ways to solve addition problems and encourage students to share their methods.
- Reinforce the idea that addition is combining.
Homework
Assignment
Students are to complete the following addition problems at home:
- 3 + 2 = ___
- 5 + 1 = ___
