Word Study — Greek Roots (bio, geo, auto, tele, phono)

Academic English is built on Greek. 'Biology' = life-study. 'Telephone' = far-sound. 'Photograph' = light-write. Once roots are known, the dictionary opens. Indirect aim: scientific literacy, preparation for Greek and Latin study, etymological joy.

• Framework: Montessori
• Unit: Language
• Learning area: Word Study

• Root cards: bio (life), geo (earth), auto (self), tele (far), phono (sound), photo (light), hydro (water), micro (small), macro (large), therm (heat)
• Etymology dictionary
• Word family sheets
• Science textbook for examples

Instructions

1. Present 'bio' = life. Word family: biology, biography, biopsy, biome. 2. 'Geo' = earth: geology, geography, geometry. 3. 'Auto' = self: automobile, autograph, autonomy. 4. 'Tele' = far: telephone, television, telescope. 5. Combine: 'autobiography' = self-life-writing. 6. Find each root in a science textbook. 7. Create a word family chart. 8.
