Here’s a simple LOGO Christmas Tree.
What can you do to change it?

VARIABLES
If you want to repeat your piece in different ways, eg different sized circles, you can use a variable in your procedure. It’s a bit like “fd” needs a number with it to tell it how far to go.
Then when you write “dot” in your program, you need to give it a number, which will be its size, eg dot 40
Basic moves and turns:
Forwards fd 40
Backwards bk 30
Turn right rt 90
Turn left lt 90 (letter l and letter t, not 1t)
reset = clears the screen and starts you in the middle (good for the start of the program)
setpensize 5 = change the pen width (all one word with no gaps)
colour “blue = change the pen colour (must use speech marks at the beginning of the colour) A full list of colours can be found here
To fill an area = fills the area that the arrow is in. If you want to fill inside a shape, you will have to move inside it then use fill.
** You could set up a little fillit procedure that moves inside the shape, fills and moves back again…
Notice this procedure moves up and right a little bit so you need to make sure you are in the right place when you call the Fill procedure.
setxy 100 -200 = moves the arrow to a place on the screen. If you don’t want it to draw a line there, use pu first! 0 0 is the middle of the screen – the first number is left and right; the second number is up and down. You can experiment to find out the rest!

This term we are going to learn a technique called “touch typing” where we learn to use particular fingers for letters. It may be slow at first, but the more time you spend practising, the quicker you will get.
There are also some typing games under resources on the menu bar above.
