Logo is a computer
programming language that can be used, for example, to create and manipulate
shapes
and patterns on screen or to control a screen or floor turtle.

FD 20 - moves the turtle forward 20 steps
BK 20 - moves the turtle back 20 steps
RT 90 - turns the turtle right by 90 degrees
LT 90 - - turns the turtle left by 90 degrees
Home - Returns the turtle to its home position

Logo Shapes Lesson
Plans - Linked to Numeracy
In this series of five lessons, Logo commands are introduced as pupils learn how to construct simple shapes. They proceed to investigate the rule for drawing any regular polygon. Next, they learn how to calculate the angles required to draw regular stars. Finally, procedures are introduced. Sheets for recording, and 'How to...' sheets on Logo skills, are linked to the plans.
Superlogo in Year 4 - Hildenborough School
In this unit, children learn to enter instructions to control a screen turtle. They 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. Then, they write short sequences to produce particular shapes on screen. They understand that screen steps are smaller than floor turtle steps. They produce 'crystal flowers' by repeating procedures, rotating the screen turtle through 360 degrees. l
