Which of the following is not a Tier I word example?

• A. See
• B. Happy
• C. What
• D. Molecule

Answer: (D)

Tier I words are the most common, everyday words that young readers should know without needing to sound them out. They appear frequently in basic books and everyday conversation. See, Happy, and What are all part of that everyday vocabulary you’d expect to see early on, since they express simple actions, feelings, and questions. Molecule, however, is a scientific term that describes a specific concept in science and isn’t among the words children are typically taught as automatic sight words. It shows up in science contexts and later vocabulary development, not in the core set of everyday words. So Molecule is not a Tier I word example.
