Option 3 – Binary Data Representation

Year 5-6
ACTDIK015: Examine how whole numbers are used to represent all data in digital systems.

This is a classroom learning activity for data representation of binary data that is aimed at upper primary but can be adapted easily to suit lower grades if appropriate – particularly if using the unplugged versions only.

Lesson starts unplugged and then moves to picture for students to further examine binary representation on computers.

  1. Organise students into small groups of three or four. Provide groups with a range of black and white squares: Black and white cards and a 5 x 5 design mat for them to lay tiles on the Design mat.
  2. Invite groups to fill up their board with the black and white squares to make a pattern.
  3. Ask students how they would get another group of students to create exactly the same pattern without allowing them to see the image? Note ideas on a whiteboard.
  4. Pair up groups and have them trial strategies for recreating patterns.
  5. As a whole class, discuss the strategies that worked the best.

Another version is students map out a mystery picture or pattern using binary code where the computer would process  ‘1’ for coloured in, or ‘0’ for not..
