Tutorials

A step by step guide to programming. Each set of tutorials provides tasks for the student to complete.

Flags

Flags Tutorials

Rectangles

Lines

Polygons

Stars

Repeats

Methods

Hard Problems

Flags Tutorial: Practice using graphics commands to draw the flags of different countries.

These examples provide students with the opportunity to become familiar with the basic features of the language. Each task can be completed using a sequence of commands. It is hoped that students will become familiar with the basics of the language: the use of brackets, commas, quotes and semi-colons.
