I love to save paper and being able to create a word search for students to complete online is perfect. You or your students can create their own puzzle and then share the link with others.
The Word Search Maker is a free online creator that saves the puzzle for 30 days. Create one in Aug./Sept. with student names so they can become familiar with the spelling of each other names, have students use it to create their spelling words or Words Their Way list, or use one of the many the pre-created puzzles.
