Scratch (If Statement + Project)

What are the two coordinates in Cartesian coordinates called?

• The a and b coordinates

• The horizontal and vertical coordinates

• Cartesian coordinates only have one coordinate, not two

• The x and y coordinates

What is the origin?

• Whatever position the Sprite first starts at

• The middle of the Sprite

• The top-left corner of the Stage, at coordinates 0, 0

• The center of the Stage, at coordinates 0, 0

Which code block moves the sprite to the center of the Stage?

• go to x: 100 y: 100

• go to x: 0 y: 0

• go to origin

• go to mouse-pointer

What is the difference between the "go-to" block and the "glide" block?

• There is no difference between these blocks.

• The "glide" block is faster than the "go to" block.

• The "glide" block can make a sprite follow the mouse pointer.

• The "go to" block moves the sprite instantly while the "glide" block moves the sprite gradually towards the given coordinates over a period of time.

What can you tell about the coordinates x: 100 y: -100

• It is on the left half of the Stage.

• It is on the right half of the Stage.

• It is on the top half of the Stage.

• Those coordinates depend on where the sprite currently is.

The y coordinate in a pair of Cartesian coordinates is a positive number. What can you tell about the location of this coordinate?

• It is on the left half of the Stage.

• It is on the right half of the Stage.

• It is on the top half of the Stage.

• It is on the bottom half of the Stage.

The "key left arrow pressed?" block is put inside of an "if then" block. What will happen with the code blocks inside of the "if then" block if the left arrow key is being held down?

• These code blocks will be run.

• These code blocks will be skipped.

How can you load a sprite from a .sprite2 file?

• Click the button that looks like a head ("Choose sprite from library")

• Click the button that looks like a paintbrush ("Paint new sprite")

• Click the button that looks like a folder ("Upload the sprite from file")

Which block can be used to switch a sprite to its first costume?

• The "switch costume to" block

• The "next costume" block

• The "if then" block

If a sprite is too large, how can you shrink it down using code blocks?

• The "set size to" block

• The "go to front" block

• The "next costume" block

• The "shrink" block
