This is my absolute favorite speaking game for native speakers. It was introduced to me by a science teacher at Westborough High School in Massachusetts as a short brain break. I use it sometimes to focus on spelling, as you will see in the video. Native speakers are often very reluctant to speak in class; here is an activity that will give many the opportunity to want to speak.
I have added captions so that if you teach native speakers of another language then you´ll still be able to follow along and adapt to your classes. Click here to follow a link to the video that I have uploaded to Vimeo.
