As part of a stage 3 communications unit in science we used the flag system to decode written messages as the first part of the lesson and then the class visually present a message using the flag system at the front of the class. The students made flags and presented this in groups.

Resource idea – In the “Semaphore Flag Codes” worksheets, the student must decode the sentence to reveal an interesting fact by using the code sheet. Available at

In teams, students create a maze using masking tape on the floor of your classroom/library/drama room, as well as, build an obstacle using scrap cardboard (eg. bridge, tunnel, jump etc). Teams must demonstrate how they can program through the maze using Sphero within a 1 minute time frame. If they cannot complete their own course then they cannot take part in the class challenge.

Teams then rotate and have 10 minutes to complete opposing teams obstacle courses. Whichever team completes the most courses wins!
