Compliance: Common Core State Standards for Mathematics and Next Generation Science Standards

Subject: Computer Science

Summary: This activity introduces fourth-grade students to the basics of computer science through hands-on coding projects.

Topic: Introduction to Computer Science

Learning Outcomes:

• Understand the basic concepts of computer science
• Develop problem-solving and critical thinking skills
• Learn to code using block-based programming
• Apply computational thinking to real-world scenarios

Methodology:

This activity will be conducted over a series of lessons, allowing students to gradually build their understanding of computer science concepts. The lessons will include a combination of teacher-led instruction, hands-on coding projects, and collaborative problem-solving activities.

Resources/Materials Required:

• Computers or tablets with internet access
• Block-based coding platforms such as Scratch or Blockly
• Printed coding worksheets
• Whiteboard or blackboard
• Markers or chalk

Instructions:

Lesson 1: Introduction to Coding

Objective: Introduce students to the basic concepts of coding and computational thinking.

1. Begin the lesson by discussing the importance of coding in today's world. Explain how coding is used to create websites, apps, and even control robots.
2. Ask students to brainstorm examples of everyday objects or activities that involve coding.
3. Introduce the concept of algorithms and explain that they are step-by-step instructions for completing a task.
4. Engage students in a hands-on activity where they create a simple algorithm for making a peanut butter and jelly sandwich. Use visual aids or real ingredients to demonstrate the steps.
5. Discuss the importance of precise instructions in coding and how small errors can lead to unexpected results.

Lesson 2: Block-Based Programming

Objective: Teach students the basics of block-based programming using a coding platform like Scratch or Blockly.

1. Introduce students to a block-based coding platform and explain how it works.
2. Guide students through a tutorial on the coding platform, teaching them how to drag and connect blocks to create simple programs.
3. Provide students with coding challenges where they have to use the blocks to solve puzzles or create animations.
4. Encourage students to experiment and explore different blocks and combinations to achieve desired outcomes.

Lesson 3: Applying Computational Thinking

Objective: Show students how computational thinking can be applied to real-world scenarios.

1. Present students with a problem-solving scenario, such as designing a game or creating a digital story.
2. Guide students through the process of breaking down the problem into smaller steps, identifying patterns, and creating algorithms to solve it.
3. Allow students to work in pairs or small groups to apply their computational thinking skills and create their own projects using the coding platform.
4. Encourage students to share their projects with the class and explain the algorithms they used.

Assessment:

Assessment will be conducted throughout the activity using a variety of methods:

• Observation of student participation and engagement during discussions and hands-on activities
• Review of completed coding worksheets and projects
• Informal questioning to assess understanding of key concepts

By the end of the activity, students should:

• Know: The basic concepts of coding, including algorithms and block-based programming
• Understand: How to apply computational thinking to solve problems and create projects
• Can do: Use a block-based coding platform to create simple programs and animations
