The 2-dimensional grid in Scratch, with numbers so that a position can be specified.
What is the x-y grid?
These blocks can be used to check if a sprite is touching the mouse-pointer or another sprite.

This block can send a message to another sprite and trigger an action in the sprite that receives this message.
What is broadcast?
An action that causes something else to happen. The green flag block is an example.
What is an event?
Instructions written in code, which are then run by a computer
What is a program?
One still image in a series.

Hat blocks are the blocks that start every script. They are shaped with a rounded top and a bump at the bottom — this is so that a user can only place blocks below them. Six of the eight Hat blocks are in this category.
What are EVENT blocks?
This extension lets projects interact with a webcam.
What is the video sensing extension?
A series of instructions that follow one another in order.
What is a sequence?
Computer instructions, written in plain language, used by coders to plan out their program.
What is a pseudocode?
Frequency at which frames in a sequence are displayed.
What is frame rate?
This is the color of the blocks that control a Sprite's movement. The stage has none of these blocks, as it cannot move.
What are BLUE motion blocks?
This extension allows text to be read aloud.
What is the text to speech extension?
When sets of instructions run at the same time we call this...
What is parallelism?
Evaluates to TRUE or FALSE, for example an IF ELSE statement.
What are CONDITIONALS?
A digital image stored as a matrix of pixel squares. e.g. digital photographs
What is bitmap?
This block category can make a speech bubble appear over the sprite and stays for the specified amount of time.
What are LOOKS blocks?
These green blocks can perform math functions and can select random numbers.
What are operators?
To assign an initial (beginning) value to a variable or object (to reset).
What is to initialize?
What are loops?
A digital image stored as mathematical equations for points, lines and shapes. Eg. digital illustrations and cartoons.
What is a vector graphic?
This block category includes the IF THEN and IF THEN ELSE blocks.
What are the CONTROL blocks?
Cap blocks are the blocks that end scripts. They are shaped with a notch at the top and a flat bottom — this is so blocks cannot be placed below them. One of the cap blocks...
What is stop or delete this clone?
Finding and fixing errors in a program.
What is debugging?
A variable that can be either TRUE or FALSE represented in binary as 1 or 0.
What is BOOLEAN?
