Digging for Prefixes

Mrs. Taylor introduces students to paleontology and the concept of prefixes. She explains how prefixes like 'pre', 'un', 'tri', and 're' change the meanings of base words, using examples like 'preview', 'uncover', 'triceratops', and 'rebuild'. The lesson includes a grammar challenge and a fun activity to simulate paleontology using cookies and toothpicks.
