Crossword puzzles are a great way to have our students interact with content in different ways. Not only does it provide another way of representing materials, it also provides another means of engaging students with content.
A really great online crossword puzzle maker that I found is Armored Penguin's Crossword Puzzle generator. Not only does it give teachers a chance to make an online version of a crossword puzzle, but there are literally hundreds of other crossword puzzles to choose from.
Depending on your computer lab situation, students can solve online or your can create a PDF or HTML text copy of the puzzle. This may be a great tool to use over the summer, when you are preparing those lesson plans for the fall!
