You might be wondering, “What in the world is the Green Eggs and Ham hypothesis?”

It’s a new moniker given to what has commonly been called the “constraints principle” – an instructional strategy to help promote creativity.

In my classroom, this strategy has included limiting words (story told in seven words),; time (one minute to summarize lesson to partner), or materials (small groups are given six pieces of tape, six paper clips, and six pieces of paper to build the tallest tower—while only speaking only English with each other or using gestures—and write a description of the process).

Even though I had used those lessons in the past, I didn’t realize it was an actual “principle” until I read a great free eBook from the British Council titled Creativity in the English language classroom.

Writer/illustrator Theodore Geisel was given a challenge by his publisher: Write a book small children will love using no more than 50 words (which could be repeated as often as needed). The result became a classic.

And here’s another excerpt from the article summary her findings in The Pacific Standard, Constraints Can Be a Catalyst for Creativity:
