Tips on using word search puzzles in a classroom ...
- Challenge students to use 10 or more of the terms in the puzzle to create a concept map or web.
- Have students make flash cards using the words in the puzzle and definitions they find in a book or on the Internet.
- Have your students write a report that includes a specific number (10, 15, or 20) of the terms in the puzzle.
- See who can find and define the most words (or fill in the most words) in a specific period of time.
- Have the students use the words to make questions for a Jeopardy-type game for their classmates.
- Offer extra credit! If I assign a word search puzzle as extra credit, I award 10 points to those students who find all the words. Students who find some of the words receive points based on the percentage they find. For example, if they find 90% of the words, they receive 9 of the 10 points. Download the Earth Science Word Search (pdf) and check out the second page for an example of my extra credit method. Students usually have 1-2 days to complete the word search puzzles (on their own time, not class time) and 3-4 days for the create-a-word challenge pages.
