Two of my favorite homeschooling years occurred when I used KONOS as the basis of my curriculum. I heard one of the founders of KONOS speak at a homeschooling convention and loved the slogan she used to describe her perspective (which I’m probably not getting exactly right), “God put the wiggle in children, don’t take it out.”
KONOS was based on the idea of integrated unit studies, a concept that I heartily applaud. Each unit had a theme and what we covered in history, science, literature and Bible studies was chosen to fit into that theme. While KONOS was Christian-based, I found it “easy” to adapt because the themes were built on character traits, in Hebrew, what I would call midot.
