NCCE Year 4 Repetition in Shapes

What programming language, that we have been using, is shown in the picture?

• Python

• Javascript

• Logo

What do we call a set of instructions that the logo turtle will follow?

• A demand

• An algorithm

What does the following code do?

FD 3

• Moves the turtle 3 squares forwards

• Moves the turtle 3 squares backwards

• Moves the turtle 2 squares forwards

What does the following code do?

LT 90

• Turns the turtle 90 degrees right

• Turns the turtle 90 degrees left

• Turns the turtle 180 degrees left the moves back 3 squares

What does the following code do?

bk 5 lt 90

• Moves the turtle 5 squares forward then does a quarter turn right

• Makes the turtle draw a square 5 times

• Moves the turtle 5 squares backwards then does a quarter turn left

What will the following code do?

• 
• 
• 

What mistake has the programmer made?

• Logo doesn't understand the 'bwd' command - it should be 'BK 6'

• Logo doesn't understand the 'bwd' command - it should be 'FD 8'

• They should have left more space between the 'bwd' and the 6

What shape will be made by the following code:

rpt 3 [fd 3 rt 120]

• square

• triangle

• hexagon

Which code does the exact same as:

repeat 4 [fd 3 lt 90]

• fd 3 rt 90

  bk 3 rt 90

  fd 3 rt 90

  bk 3 rt 90

• fd 4 fd 3 lt 90

• fd 3 lt 90

  fd 3 lt 90

  fd 3 lt 90

  fd 3 lt 90

Draw what the following code displays in the Logo app:

pd fd 3 pu fd 2 pd fd 3 pu fd 2 pd fd 3
