In Lesson 10 of Chapter 5 from Vocabulary from Classical Roots Book B, Grade 5 students study ten vocabulary words rooted in the Latin verbs specto ("to look at") and vigilo ("to watch"), including terms such as introspection, retrospect, spectrum, specter, speculate, surveillance, and vigilant. Students learn each word's etymology, part of speech, and meaning through example sentences, then practice identifying synonyms and antonyms and recognizing correct and incorrect usage in context. This lesson builds classical word-root skills that strengthen both vocabulary comprehension and academic reading across subjects.
