📚 Topic Summary
In Scratch, a sprite can be programmed to display numerical values, acting as a counter or a visual representation of data. This is achieved by using variables and the 'say' block to output the variable's value. This printable activity will guide you through designing a Scratch sprite that dynamically shows counts, enhancing your understanding of variables and data representation in programming.
By the end of this activity, you’ll be able to create interactive projects where sprites display scores, track items, or represent any numerical information you desire!
🧮 Part A: Vocabulary
- 🔢 Variable: A named storage location in a computer's memory that can hold a value.
- 💻 Sprite: A programmable object or character in Scratch.
- 💬 Say Block: A Scratch block that makes a sprite display text.
- ➕ Increment: To increase the value of a variable.
- ➖ Decrement: To decrease the value of a variable.

✍️ Part B: Fill in the Blanks
In Scratch, we use a ______ to store numerical values. To make our sprite display this value, we use the ______ block. When we want to increase the value, we ______ it. If we want to reduce the value, we ______ it. The character in Scratch is called a ______.
🤔 Part C: Critical Thinking
How can you use a sprite showing counts to create a simple game in Scratch? Describe the game mechanics and how the sprite's count would be used.
