Do this: Read each name. Point to that part in your own project.
A SpriteA character or object you can give instructions to.Exactly: A programmable character or object in Scratch.Mix-up alert: A sprite is not the stage. It is an object that appears on the stage.See this in Key words is a character or object you can program in Scratch. Its costume is how it looks.
The StageWhere you watch the action in Scratch.Exactly: The area where sprites appear and their visible actions take place.Mix-up alert: A screenshot of the stage shows a moment, not every instruction in the script.See this in Key words is the area where you see sprites and what they do. It is not the stack of instructions.
A BlockOne shaped piece of Scratch code.Exactly: A code piece used to build a Scratch script, such as a movement instruction or a start block.See this in Key words is a shaped piece of Scratch code. For example, change x by 20 tells a sprite to change its horizontal position.
A ScriptA stack of connected code pieces.Exactly: A connected stack of blocks in Scratch. In our small scripts, a sprite carries out the instructions in order.See this in Key words is a connected stack of blocks. Our small scripts give a sprite instructions to carry out in order.
An event is a trigger that starts a script. Clicking the Green flagA start signal you click.Exactly: Clicking the green flag is an event that starts scripts headed by when green flag clicked.Mix-up alert: Clicking the flag does not itself reset the sprite's position. The script needs a position-setting block for that.See this in Key words starts a script headed by when green flag clicked. This start block says when its stack begins.
Do this: Name the sprite, stage, and script in the story.
Mina uses the online Scratch editor on a Chromebook to make a club mascot move. The mascot is the SpriteA character or object you can give instructions to.Exactly: A programmable character or object in Scratch.Mix-up alert: A sprite is not the stage. It is an object that appears on the stage.See this in Key words. She connects when green flag clicked, go to x:0 y:0, and change x by 15. That stack is a ScriptA stack of connected code pieces.Exactly: A connected stack of blocks in Scratch. In our small scripts, a sprite carries out the instructions in order.See this in Key words made of three BlockOne shaped piece of Scratch code.Exactly: A code piece used to build a Scratch script, such as a movement instruction or a start block.See this in Key words. She predicts the movement, then clicks the green flag. She watches the result on the StageWhere you watch the action in Scratch.Exactly: The area where sprites appear and their visible actions take place.Mix-up alert: A screenshot of the stage shows a moment, not every instruction in the script.See this in Key words.
Do this: Explain why a good-looking mascot is not enough.
A costume changes how a sprite looks. A nice costume does not prove that its ScriptA stack of connected code pieces.Exactly: A connected stack of blocks in Scratch. In our small scripts, a sprite carries out the instructions in order.See this in Key words works. Read the blocks, predict their result, and run the script. Compare what happens on the StageWhere you watch the action in Scratch.Exactly: The area where sprites appear and their visible actions take place.Mix-up alert: A screenshot of the stage shows a moment, not every instruction in the script.See this in Key words with your prediction.

Card 1 of 15
0 Know it0 Still learning
Who does the action?
On the card: Enter or Space flips. Left and Right move. After revealing, 1 marks Still learning and 2 marks Know it. Tab reaches every control.
What is a sprite?
A character or object you can program in Scratch.
Where do you watch a sprite's actions?
On the stage, the area where sprites appear and act.
What is a block?
One shaped piece of Scratch code.
What is a script?
A connected stack of blocks.
What starts a script headed by when green flag clicked?
Clicking the green flag.
What does event mean here?
A trigger that starts a script, such as clicking the green flag.
What does a sprite's costume describe?
How the sprite looks, not the instructions it follows.
Does a nice costume prove the script works?
No. Read and predict the script, then run it and compare the result.
Mina programs a club mascot in Scratch. Which part is the mascot?
The sprite: the character or object being programmed.
How does one block differ from a script?
A block is one code piece. A script is a connected stack of blocks.
What action does change x by 20 tell a sprite to do?
Change its horizontal position.
What does when green flag clicked tell you about its stack?
When that script starts: when the green flag is clicked.
After predicting and running a script, what should you compare?
What happens on the stage with your prediction.
Mina connects the flag start, go to, and change x blocks. Is the connected whole one block or a script?
A script made of three blocks.
Why is choosing a nice costume not enough to check movement code?
A costume describes looks. You must read, predict, and run the script to check its actions.
