Subject: Computer Studies

Class: Primary 4

Term: Third Term

Week: 11

Topic: Introduction to Scratch Programming

Sub-topic: The 3S of Scratch and Identifying Components of the Scratch Interface

Duration: 40 minutes

Behavioural Objectives:

By the end of the lesson, pupils should be able to:

1. Define Scratch programming.
2. Identify the 3S of Scratch.
3. Name and describe the components of the Scratch interface.
4. Explain the differences between visual and text-based programming languages.

Keywords:

• Scratch
• Programming
• Interface
• Blocks
• Scripts

Entry Behaviour:

Pupils have basic knowledge of using a computer and have been introduced to simple computer applications like Microsoft Word and Paint.

Learning Resources and Materials:

• Computers with Scratch installed
• Projector
• Whiteboard and markers
• Lagos State Scheme of Work for Primary 4
• Scratch programming manual

Building Background / Connection to Prior Knowledge:

Ask pupils if they remember the basic components of a computer and some applications they have used before. Connect these to the idea of creating programs using Scratch.

Embedded Core Skills:

• Critical thinking
• Problem-solving
• Creativity
• Collaboration

Learning Materials:

• Lagos State Scheme of Work
• Scratch programming manual
• Projector
• Computers with Scratch installed

Presentation:

Step 1: Revision of the Previous Topic (5 minutes)

• The teacher revises the previous topic, which was “Launching of Microsoft Excel and Its Basic Functions.”
• Quick recap questions:
  • How do you open Microsoft Excel?
  • Name one function of Excel.

Step 2: Introduction of the New Topic (10 minutes)

• Introduce Scratch programming: “Scratch is a fun way to learn programming by snapping blocks together.”
• Explain the 3S of Scratch:
  • Sprites: Characters or objects in Scratch.
  • Scripts: Instructions that control the sprites.
  • Stage: The area where the action happens.

Step 3: Exploring the Scratch Interface (15 minutes)

• Demonstrate the Scratch interface using a projector:
  • Toolbar: Where you find tools to save, load, and create new projects.
  • Blocks Palette: Contains code blocks for programming.
  • Scripts Area: Where you snap blocks together to create code.
  • Sprites Pane: Shows all the sprites in your project.
  • Stage: Displays the outcome of your scripts.

Teacher’s Activities:

• Demonstrate how to open Scratch on the computer.
• Show pupils how to navigate the Scratch interface.
• Explain each component clearly and slowly.
• Encourage pupils to ask questions.

Learners’ Activities:

• Follow along with the teacher on their computers.
• Explore the Scratch interface.
• Ask questions if they are unsure about anything.

Assessment:

• The teacher asks pupils to identify parts of the Scratch interface.
• Pupils will name the 3S of Scratch and explain their functions.
