120 Lessons from Open Source Phonics is a completely free phonics curriculum designed to guide beginning readers step by step. It includes sequential lesson scripts, printable readers, and practice pages that systematically introduce sounds, blends, and common patterns. Parents appreciate that everything is open-source, clearly laid out, and doesn’t require expensive materials or proprietary books. It’s best for early readers in kindergarten through early elementary, especially in one-on-one settings. The layout is functional rather than glossy, but that simplicity helps many families focus. Printing lessons and keeping them in a binder, then revisiting tricky ones as needed, turns this into a full foundational program.
