Using context clues is a skill that we teach many of our students with semantics goals. Practicing it can get repetitive - which is why I wanted to make an activity that had some more room for creativity and fun. Included in the powerpoint are: an introduction/review of context clues and its importance, a step-by-step walkthrough example of the activity, and 6 perfectly ridiculous and original nonsense sentences that I created to teach each student how to identify a word's part of speech (and therefore a clue as to its potential meaning) based on the clues in the sentence.
Although there are only 7 sentences total (with the example), it takes a while to break down each word in each sentence and come up with synonyms to give it meaning, so it gives them plenty of time to practice and learn.
This activity does assume that each student is familiar with parts of speech and their rules - it may be beneficial to do a quick review before beginning.
I've used this with a few students now, and they seem to really enjoy it - especially the mad-lib-esque component at the end of each sentence.
