Spotted on YikYak under the hashtag #ReclaimtheMirror2015. It reminds me of our IB Math Studies logic unit (which I won’t get to teach next year unless we can somehow swing one cohort of IB Math Studies and one cohort of IB Math SL for the Class of 2015).
1) Translate the two sentences into logical symbols.
2) Find the converse, inverse, and contrapositive of each sentence.
3) Are the two sentences logically equivalent? Create a truth table to check.
