And, let's be honest, these 40-minute periods are killer: By the time students get to class and get settled, there simply is not time to embark on such grandiose adventures!
Nevertheless, it was a step outside my comfort zone (which means I grew a bit!), and I do think some of the students enjoyed using the technology to document their group's work. Next time, I would spend more time brainstorming success criteria for what makes an effective Flipagram, and then have students work in pairs to complete the task and record their work.
