Description

This activity helps students learn how computers "compress" text by identifying repeating patterns of letters, words, and phrases. Students use poems or nursery rhymes as their source text, draw boxes around repeating parts, and use arrows to point to earlier parts of the text that can be used to "uncompress" the text. The boxes and arrows are then related to the numbers that computers use in compression. An extension has students try compressing a much longer story, "The Three Little Pigs."
