Izzit offers free daily current events lessons that are not only kid-friendly, but also teacher-friendly. Here's how it works (the following text is from Izzit):
The FREE lessons are updated daily throughout the school year. Each
lesson includes a news article and discussion questions designed to
promote critical thinking, challenge assumptions, and stimulate class
discussion. Note: Each new lesson remains on the website for one week.
