I've put together a lesson on metaphors for a bright Year 7 class but, despite a long search on the Internet, I can't find a really good poem to use. There are plenty of poems there, but nothing that really jumps out at me. I was hoping to find something fairly humorous and perhaps by a poet that the class would recognise. The trouble with the Internet, I think, is that there is too much to look at. Can anybody recommend a particularly enjoyable poem to use? Thanks in advance.
