This short powerpoint outlines the different types of headlines (puns, word/letter play, alliteration and rhyming) along with examples on each page.
Many of the pages are animated to run automatically.
Useful, I'm going to try to alter the timings so it works. Homophones are actually a type of homonym so I think that is fine! I agree that copulation is not ok for KS2 though. Without that, a time saving resource.
I have just adapted this for my Year 5 class. It was a great basis for a presentation and it saved me from staring from scratch. However I did need to make the changes mentioned above (eg got rid of copulation, changed homonyms to homophones, and corrected lightning!).
