The digital world is as real as the physical one, although it may not seem so sometimes. In order to help our young students understand that you have to be a responsible citizen also online, Edudemic published this interesting guide that you can check here.
Moreover, Edutopia published some resources around this.
And last but not least, Wikipedia gives ideas to develop students’ literacy about statistics (or big data, under its recent and fashionable name…)
Hope you find it useful!
