Rachel Greene is a homeschooling parent and the founder of ST Math Homeschool. Teaching her own children at home, she discovered that a good diagram beats a paragraph of definitions every time — and built the site around that idea.
She writes every guide herself, draws the visuals, tests explanations with real learners, and answers reader questions at rachel@lostorfound.org.
