Algorithm (Instructions) for a Pirate Treasure Map

An algorithm is the set of instructions needed to complete a task.

This is an activity to be used away from the computer.(Unplugged computing)

• Children to use and understand control language.
• They move the mini robot or floor turtle around the pirate map to hide the treasure.
• They write the route or algorithm on a work sheet so the treasure can be found by someone else.
• They write where the treasure is on the back, then swap sheets with someone.
• If the instructions lead to the wrong place they can fix or debug their algorithm.
• Children can design their own robots or use the printouts.

Here are the * I can statements*

I can use numbers in instructions.
I can use a 90 degree turn.
I know that control instructions must be precise and clear.
I can predict what my turtle will do when using a verbal or written algorithm.
I can follow a series of simple commands(algorithm) to move around a course.

There is a pdf file and a PowerPoint presentation that can be used as a lesson starter.
I have used this activity with Year 1-4
