LOGO

Today in Maths we are using LOGO to draw polygons! Accuracy is the key, one little mistake and you will be scratching your heads.

The picture above was created by defining a circle. First type:
to circle
repeat 360[fd 1 rt 1]

Now type in circle to test your instructions. Did the circle draw okay?

Next, use the circle to draw a repeating pattern by entering these instructions:

to sunflower
circle
pu
rt 321
pd
sunflower
end

These just happen to be the instructions we tested this afternoon - what we were really interested in was creating regular polygons, but we couldn't resist repeating them to make interesting patterns! We might make Christmas decorations...

Please ask for permission before installing LOGO at home!

rt - right turn
lt - left turn

end

You can also change the background colour and the colour of the pen! Try going to the help menu and clicking on demo - LOGO can produce some tricky designs.
