Common Misconception
Students grab the nearest noun instead of the descriptive clue. Guide them: "Does that word describe the cauldron, or is it just another thing in the room?"
Scaffolding (Tier 2/ELL)
Provide a 2-choice word bank (e.g., "Does famished mean full or starving?") and pre-highlight signal words in neon yellow on sentence cards.
Sleuth Challenge
Have fast-finishers write their own Halloween sentence featuring an antonym clue for the mystery word luminous or petrified.
