Sequencing Blockly - 2

You write this sequence: turn left, move forward, turn right, move forward. What shape will the character make?

• A straight line

• A curve

• A right angle turn

• A circle

Which command must come first if you want the character to avoid a wall directly in front?

• move forward

• turn right

• repeat

• say hello

What will this code do?
Repeat 2 times:
Move forward
Turn right

• The character moves in a U-shape

• The character goes back to the starting point

• The character turns in a square pattern

• The character moves forward, turns right, and repeats this twice

A maze has two forward steps, then a left turn. Which is the correct command sequence?

• move forward, turn left, move forward

• move forward, move forward, turn left

• turn left, move forward, move forward

• turn right, move forward, turn left

What will the character do?

• Move forward 5 steps and turn left in between

• Move forward 3 times and turn left 2 times

• Turn left 3 times and move 2 steps

• Repeat all steps 5 times

What’s the difference between these two codes?
Code A - Left, Code B - Right

• Code A turns twice after one move; Code B moves twice, then turns

• Code A is faster

• Code B turns more

• There is no difference

Which block sequence is most efficient to move in a square?

• Use 4 move forward blocks and 4 turn left blocks

• Use repeat 4 times: move forward, turn left

• Use repeat 2 times: move forward, turn right

• Use turn left four times only

What will happen if the repeat block is placed outside the when run block?

• The code repeats forever

• The code does not run

• The code runs twice

• The code runs slowly

You accidentally switch move forward and turn left inside a repeat. How will this affect the output?

• The program still runs as planned

• The character will turn before moving, changing its path

• The repeat block fixes the order

• It becomes faster

Why is the correct sequencing of blocks important, especially in loops?

• The loop will crash if the order is wrong

• The loop will make mistakes in colors

• The loop repeats the exact order of blocks, so wrong order = wrong results

• The loop won’t care about block order
