Many parents would like to educate their kids in Christian theology, apologetics, and worldview, but don’t know where to start or where to obtain good resources. If you are looking for a curriculum for kids age 4-14, check out http://www.foundationworldview.com. It’s on online curriculum using videos, worksheets, and parent resources. There are four courses:

1. Worldview (ages 4-8)
2. Comparative Worldview (ages 8-12)
3. Studying the Bible (ages 8-12)
4. Careful thinking (ages 10-14)

Ratio Christi has also put together a list of resources by education level:
Elementary school
Middle School
High School

Finally, check out a video I recorded a few years ago showcasing the theology and apologetics resources I have used with my kids over the years.
