Oftentimes students (and let's face it, even many adults) do not know the difference between colloquialisms, slang words, and jargon. I have created this PowerPoint presentation to guide them through, using cartoons, definitions, examples, and little "tricks" to demystify and illustrate the difference.
This PowerPoint is made up of seventeen slides, but it would be more accurate to say that there are six full "content" slides. (The other slides simply help ease the transition from definitions to examples.)
This lesson can be given within 30 minutes and referred to later to reinforce learning. Slides have been designed to allow for attractive print versions so they may then be put up in the classroom to support learning, as well. In no time, your students will stop their head-scratching trying to figure it all out.
