Text Compression

The second lesson in a unit of 15 introduces pupils to text compression. The class begins with discussing how they already use text compression when sending text messages. Pairs learn more about the subject as they work to compress a poem using an online tool. The pairs then develop their own approach to text compression and share their plan with other groups to use.
