1. Binary pixel challenge 2
To know that pixels can be represented as RGB and binary values

2. What is a pixel?
RGB Generator

3. Binary pixel challenge 2
Your challenge: To use the RGB colour values to find the colours of the flag. Convert the binary code to RGB values to find the colours of the flag.
(you may wish to use the pixel challenge support sheet to help you convert from binary)
Can you predict colour by looking at the numbers?
Use the closest available colour to colour in each flag.
Introduce the task giving out as little information as possible. Allow pupils to try to complete the task and monitor their choice of code arrangements.
Encourage a logical approach and praise perseverance.
Pupils may develop a code that works up to the number 5 and then get stuck. Encourage them to think laterally using computational thinking skills to figure out a solution to their problem. Let them know that this skill is known in computing as debugging.
When pupils have tried for a sufficient amount of time, introduce the clues one at a time. Ask the pupils if they are ready for a clue and read the room to see if they are willing to try without clues.
Computational thinking skills
Abstraction - ignoring the information that isn’t needed
Decomposition - Breaking down into smaller parts that are easy to deal with
Pattern recognition - Finding patterns in decomposed parts
