Each slide has 2 exercises. There are 7 total slides.Slides rotate every 10 seconds. Slides can also be paused (and exercises are still playing on video) and this stops the slides from rotating.I use them in activities where I allow the students to choose which exercise they complete and activities where one student completes one exercise and the other student completes the other exercise.Examples:1. Students play RPS, winner completes exercise on the left, loser completes exercise on the right.
