| In this unit children
learn to enter instructions to control a screen turtle and will
compare the operation of the screen turtle with a floor turtle. They
learn how to write a procedure that 'teaches' the computer a new word
and will be asked to write short sequences to produce particular
shapes on screen. They understand that screen steps are smaller than
floor turtle steps and will be asked to repeat procedures to produce
'crystal flowers' by rotating the screen turtle through 360 degrees.
Children will be able to apply what they have learnt in this unit
when working with shapes and space in mathematics. |
