This is a simplified version of the programming language Logo. Use it to draw shapes by moving the turtle (arrow) around the screen using the following commands:

Example: fd 10 will move the turtle forward ten steps.

Example: bk 5 will move the turtle backwards five steps.

Example: rt 90 will turn the turtle 90^{o} to the right.

Example: lt 45 will turn the turtle 45^{o} to the left.

The turtle can move without drawing a line.

Example:

repeat 4[fd 10 rt 90]

will draw a square.

Example: pc 2

0 = black, 1 = blue, 2 = red etc

Logo is a simple programming language devised by Seymour Papert for educational purposes. Students can control the movement of a 'turtle' which draws lines on the screen. Students learn about lengths and angles while creating diagrams and patterns. The learning takes place as students experiment, get feedback and revise their actions in a non-judgmental environment. Students develop a much better understanding of angles being an amount of turning than they do from more traditional, static exercises.

Logo is a wonderful application to use when learning about the properties of shapes and angles. Using the repeat command to draw a triangle usually results in a significant and poignant learning moment as students grasp the difference between the internal and external angles.

You can find in the left panel above instructions and a series of challenges for the student who has not used Logo before. Click the blue buttons to move through the challenges. Students can use the snipping tool to capture pictures of their work which they can paste into their notes. Please send Transum pictures of anything magnificent you produce with this application.
