Which word is a high-frequency word that the student correctly read in other sentences?

• A. a
• B. to
• C. dog
• D. street

Answer: (B)

High-frequency (sight) words are the words most common in early texts that kids are encouraged to recognize instantly, without sounding them out, to read smoothly and quickly.

In this item, recognizing the word that shows up often across many sentences is the key. The word to pick is the one the student can read automatically in different contexts. That word is a very common preposition, used repeatedly in writing, so noticing it quickly in various sentences demonstrates fluent recognition. The other options are less likely to be seen as instantly recognizable across many sentences in early reading materials: a and the are common sight words too, but this context points to the frequent preposition as the best example of automatic recognition across sentences, while dog and street are more specific content words that don’t appear as reliably in a wide range of early texts.
