Word clouds may be easy to understand but thinking of ways to integrate them into the classroom may be a bit challenging. One example in my classroom is highlighting frequent words in our reading groups. Our curriculum has web based versions (PDF) of each guided reading book we use. I can copy the text from a guided reading book and use a word cloud tool to create a quick visual cloud of the words in the text. This will highlight the most common words that will appear during reading.
You could have students take their blog posts and turn them into a word cloud to see the most frequent words. They could put those highlighted words in alphabetical order.
Students could take a text, blog, our personal writing piece and make a quick word cloud. This word cloud could serve as as story starter for creative writing.
Students could make word families to display with a word cloud.
Parts of speech could be made into word clouds.
Feel free to comment on ways that you have used word clouds in your classroom.
