📚 Topic Summary
Variables are like containers that hold information in a Scratch program. This information can be numbers, words, or anything else you want to store. You can change the value of a variable as your program runs, making them super useful for things like keeping score in a game or tracking the number of times something happens. Think of them as labeled boxes where you can put things in and take them out!
In Scratch, you can create variables and use blocks to set their values, change their values, and display them on the screen. Understanding variables is key to creating more complex and interactive projects! Let's dive into some practice activities to help you master this important concept.
🧠 Part A: Vocabulary
Match the term with its definition:
| Term |
Definition |
| 1. Variable |
A. A named storage location that can hold a value. |
| 2. Initialize |
B. To set a variable's starting value. |
| 3. Increment |
C. To increase the value of a variable. |
| 4. Decrement |
D. To decrease the value of a variable. |
| 5. Data Type |
E. The kind of data a variable can hold (e.g., number, text). |
(Match the numbers 1-5 with the letters A-E)
✍️ Part B: Fill in the Blanks
Variables are like labeled __________ that hold information. We can __________ a variable to give it a starting value. To increase the value of a variable, we __________ it. To decrease the value, we __________ it. The type of information a variable holds is called its __________.
🤔 Part C: Critical Thinking
Explain a situation where using a variable in a Scratch game would be helpful. Give a specific example of what the variable would store and how it would be used.
