Everfi: http://everfi.com/  is an online self-paced curriculum that students can use to learn a variety of topics. They have units in health, financial literacy, digital citizenship and more. This is free to teachers due to the fact that they allow corporate sponsors to advertise. Teachers must create accounts in order to access the materials. Some units are available when you first login and others can become available if you “request access”. I did this on a couple of units and heard back before the end of the day. Most of their units are designed for middle or high school, but there are a couple for elementary also. The video game style of delivery (must unlock levels to move on, earn certificates as you go) would be engaging to students and teachers will appreciate the dashboard where they can track student progress.

Update: They added new free curriculum. See all free offerings HERE.
