The Wizard of Ozo

Years 3-4

Using OzoBots students move an Ozobot about a map with coordinates.

This lesson idea was created by Ben Jucius.



  • A3 paper to create map with coordinates.
  • Clear plastic sleeves
  • The OzoBot kit, inc. pens, paper,
  • A simple series of tasks to perform at grid locations.
  • A story of The Wizard of Oz. A short example can be found here.

Prior Student Learning


Some prior knowledge of simple grid maps.

Learning hook

Watch read or otherwise engage with the story “The Wizard of Oz”. Using the Ozobot, pens and paper, have students investigate through impromptu experiments with the colour language of the Ozobot.

Learning map and outcomes

  • Students become familiar with Ozobots and the Ozobot colour language.
  • Students create a simple grid map of “Oz”.
  • Students develop tasks for their Ozobot to perform at different locations on their map.
  • Students develop an algorithm using the colour language to perform the tasks
  • Debug algorithms
  • Students share and reflect on their Ozobot’s performance.

Learning input

Students learn how to calibrate Ozobots.

Students learn Ozobot colour language.

Explain concept of debugging to create the most effective solution. This can include making lines thick enough to correct colour sequence.

Learning construction

Students can work individually or collaboratively with one or more Ozobots.

Students are encouraged to experiment with the abilities of the Ozobots.

Students create a grid map of Oz

Students place the map into a plastic sleeve and create paths through Oz.

The students perform tasks at each coordinate as per the teacher task.

Students develop and share their own sequence of tasks.

Students can make costumes for their Ozobots.

Students critique their performance based on efficiency and entertainment value.

Learning demo

Students demonstrate to small groups during the development stage offering positive criticism regarding possible improvements.

Students share each other’s tasks and maps.

Students may perform to the whole class. Possibly, students create a video event to share with others at a later date.

Learning reflection

Students critique their results about what was good, bad and can be improved upon.
