Year 4 – Controlling Objects on the Screen

Year 4 have been programming procedures in LOGO to create a firework display.

Procedure for a Firework Display

repeat 16 [fd 70 rt 160]
pu
end

to move
fd 100
fd random 50
rt random 360
end

to red
setpc [255 0 0]
end

to sky
setfloodcolor[0 0 0]
fill
end

to yellow
setpen [255 255 0]

The children explored how using a repetition of a repeat loop helped them to draw 2D shapes must faster.

Eg for a square it would be repeat 4 [fd 100 rt 90]
