PBS Kids is a great resource for elementary school teachers, students, and parents. Recently I came across the PBS Kids Get Your Web License activity. In this activity students are asked a series multiple choice questions about web safety and other web-related topics. As students answer the questions they move around a “track” on the PBS Kids website. When students have answered all of the questions correctly they get their web licenses.

Applications for Education
The PBS Kids Get Your Web License activity could be a great summative activity to use after teaching students about safe web browsing habits.
