Using Word Searches in Your Classroom
Word search puzzles are more than busywork. When tied to vocabulary instruction, they activate a form of spaced retrieval practice — students scan for a target word, reinforcing the orthographic form of the word in memory. Research on word searches suggests they work best when paired with meaning instruction: have students write a sentence for each found word, or define words from context before the search.
