📚 Topic Summary
Learning to break down a big problem into smaller, manageable parts is a super important skill in computer science, and it's called decomposition! For first graders, we can teach this idea without any computers at all – that's what 'unplugged' means. The 'Sandwich Task' is a fantastic unplugged activity where students learn to think like a computer scientist by breaking down the process of making a sandwich into a clear, step-by-step list. This helps them understand that complex tasks become much easier when you tackle them one small piece at a time, just like following a recipe!
🧠 Part A: Vocabulary
Match the word to its meaning!
- 🧩 Decomposition: Breaking a big problem into smaller, easier-to-manage parts.
- ➡️ Algorithm: A set of step-by-step instructions to solve a problem or complete a task.
- 🔌 Unplugged: Learning or doing an activity without using a computer or electronic device.
- 🔢 Sequence: The specific order in which steps or events happen.
- ✅ Task: A job or something that needs to be done.

(Words: steps, decomposition, algorithm, break down)
Making a sandwich is a great way to learn about decomposition. First, you need to break down the big job into smaller steps like getting bread, adding filling, and cutting. This step-by-step process is called an algorithm.
🤔 Part C: Critical Thinking
Imagine you want to build a tower with blocks. What are three small steps you would take to complete this big task? Think about the order!
- 1️⃣ First, I would...
- 2️⃣ Next, I would...
- 3️⃣ Finally, I would...
