Finite state automata (FSAs) sound complicated, but the basic idea is as simple as drawing a map.
This fun activity is based around a fictitious pirate story which leads to the unlikely topic of reasoning about patterns in sequences of characters

- [Requires Java installed] SwissEduc has a programming environment called Kara, which is a programmable ladybird robot that has been developed to help teach Computer Science concepts such as finite state machines, turing machines. The variations of this program are given below:
- [Registration and software download required]The Greenroom resources area using the Greenfoot software has the treasure finding finite state automata exercise you can download and use in the Greenfoot environment. If you are a teacher, you can apply easily to join and use the resources there.
