Secular homeschool curriculum is hard to find, I know this because I am looking for it too. Find what works for you...
Hands-On History. Timeline of Canada. Canadian Adventure – interactive, virtual trip across Canada. And more!
You don’t necessarily need to find a curriculum to teach history or social studies in your homeschool.
History Quest: Early Times is a read-aloud history book for children.
I have found it is best to ask what they are interested in, and then teach them around their interests.
