Vocabulary Pre-Teaching and Text Coverage in a Latin I Passage
You are adapting a 120-word passage about a Roman school day for Latin I. A corpus check shows 32 running words outside the class's 1,000-word core list. Of these, 14 are proper names or transparent cognates such as Roma, grammaticus, and tabula; 11 occur only once; and 7 recur. Your department's reading guidance targets 95% known-word coverage for independent reading and 90% for supported reading. You have 20 minutes of pre-reading time and a glossary margin. Students will hear the passage read aloud once and then translate it in pairs. A colleague proposes pre-teaching all 32 words with flashcards before students read.
1. Calculate the approximate coverage under the colleague's plan and under a targeted plan, and explain why pre-teaching all 32 words may still fail.

If all 32 words were genuinely unknown, coverage would be (120−32)/120 ≈ 73%, far below both the 90% supported-reading and 95% independent-reading targets. Even counting the 14 names and transparent cognates as accessible, 18 opaque words remain: (120−18)/120 = 85%, still below 90%. Pre-teaching all 32 also ignores whether students retain the glosses under reading load; flashcard recognition does not guarantee meaning access in connected text. The targeted plan should reduce opaque unknown words to about 6 for 95% coverage or 12 for 90% coverage. Because the passage is supported and read aloud, 90% is a realistic target; the teacher should pre-teach the 7 recurring words and gloss selected once-only words, while treating transparent cognates and names as accessible with brief pronunciation support.
2. Which words would you pre-teach, which would you gloss, and which would you leave to context? Justify your choices.

Pre-teach the 7 recurring words first: they carry the highest return because students will meet them multiple times in the passage. Prioritize words that are structurally important-verbs of saying, teaching, or writing, and nouns that anchor the school-day setting-over low-frequency adjectives. Gloss the 11 once-only words in the margin, especially those that are not inferable from context or cognates; a gloss costs less time than a flashcard cycle and keeps the pre-reading phase short. Proper names such as Roma and transparent cognates such as grammaticus and tabula can be handled with a quick pronunciation and word-family note, not full pre-teaching. Leave context-inferable words unglossed when surrounding syntax and familiar words narrow the meaning. The principle is to spend pre-reading time on high-frequency and meaning-critical items, not to equalize treatment of all 32 words.
3. How would you check comprehension without requiring word-by-word translation?
Read the worked answer
Use a few targeted tasks that reveal whether students understand the passage's structure and main ideas. Ask for the setting, the main actors, and the sequence of two or three events; ask one reference question about a pronoun or repeated noun; and ask one inference question that requires connecting two sentences. Students can answer in English or with short Latin phrases. During pair translation, circulate and listen for whether students are using the glosses strategically rather than copying them. After reading, ask students to name one unknown word they inferred from context and explain the clue. This checks comprehension and strategic reading without turning the lesson into a vocabulary quiz or requiring every word to be translated. It also gives the teacher evidence for which glosses were unnecessary.
