I love making my kids use crossword puzzles in class to review vocabulary. There are tons of free websites out there, but I keep finding myself heading to this link. It makes it easy to input the words, definitions, adding a title, and choosing whether or not to include a word list, answer key, etc.
At the end of the chapter I pull up the site, and type in the information. It allows me to save it as a PDF for next year. The kids are actually excited to do it because it is fun! It's a great way to review!
Do you use crossword puzzles too? What other games do you play for vocabulary?
