I have recently programmed a brand-new online tool which allows teachers and students to create interactive crossword quizzes that can be embedded on your own website, blog or VLE. I will be using it as a revision tool in the lead-up to this year’s summer exams but it is also going to be useful for end-of-unit factual tests.
You can also export your crossword as a .pdf worksheet!
You can try it out for yourself here: HTML5 Crossword Generator from ClassTools.net. There is a sample quiz here.
