Exploring Coordinates in Scratch

What are the X and Y axes in a coordinate system?

• The X axis is horizontal and represents the independent variable; the Y axis is vertical and represents the dependent variable.

• The X axis is used for time and the Y axis is used for distance measurements.

• Both axes represent independent variables; the X axis is always longer than the Y axis.

• The X axis is vertical and represents the dependent variable; the Y axis is horizontal and represents the independent variable.

How do you represent a point using coordinates in Scratch?

• A point is represented by its radius and angle in Scratch.

• A point is represented by its color and size in Scratch.

• A point is represented by its name and type in Scratch.

• A point is represented by its x and y coordinates in Scratch.

What is the range of X coordinates in Scratch?

• 0 to 500

• -240 to 240

• -300 to 300

• -100 to 100

What is the range of Y coordinates in Scratch?

• -100 to 100

• 0 to 360

• -90 to 90

• -180 to 180

How do you create a sprite at specific coordinates in Scratch?

• Set the sprite's position using the 'change x by [value]' block.

• Use the 'move [value] steps' block to position the sprite.

• Use the 'go to x: [value] y: [value]' block to position the sprite.

• Drag the sprite to the desired location on the stage.

What block would you use to set a sprite's position in Scratch?

• change size by 10%

• turn left by 15 degrees

• go to x: [ ] y: [ ]

• move 10 steps

How can you move a sprite to a new coordinate in Scratch?

• Use the 'go to x: [value] y: [value]' block.

• Use the 'set x to [value]' block.

• Use the 'change y by [value]' block.

• Use the 'move [value] steps' block.

What happens if you set a sprite's X coordinate to 0?

• The sprite moves to the center of the screen.

• The sprite disappears from the screen.

• The sprite moves to the left edge of the screen.

• The sprite moves to the right edge of the screen.

How do you draw a square using coordinates in Scratch?

• Use the pen to draw a square by moving to coordinates (x: -50, y: -50), then (50, -50), (50, 50), (-50, 50), and back to (-50, -50).

• Draw a square by moving to coordinates (x: 0, y: 0), then (100, 0), (100, 100), (0, 100), and back to (0, 0).

• Draw a square by moving to coordinates (x: -25, y: -25), then (25, -25), (25, 25), (-25, 25), and back to (-25, -25).

• Use the pen to draw a triangle by moving to coordinates (x: -50, y: -50), then (50, -50), (0, 50), and back to (-50, -50).

What is the purpose of the 'go to x: y:' block in Scratch?

• To change the sprite's costume.

• To increase the sprite's size.

• To play a sound when clicked.

• To move a sprite to a specific position on the stage.
