Adaptive teaching
Pupils needing extra support
- Could use the Resource: Binary text table (support) alongside the Activity: Binary text (support) to convert individual letters into 8-bit binary step by step while creating a simple message.
- Could create their name instead of a full message to reduce the amount of encoding required while still meeting the success criteria.
Pupils working at greater depth
- Should explain how ASCII represents text by describing how characters are converted into binary and how start and end text codes are used.
- Could extend their message by adding additional words or punctuation and checking accuracy by decoding it back into text.
