Product Description
Need more resources when you are teaching logic to your geometry classes? Are you teaching geometry for the first time and need to wrap your mind around the concepts yourself? The books never seem to have enough of the same type of problem for the students to practice so I started making my own.

This activity is a new version (all new examples) of an old one that I still have posted. It contains 20 conditional statements that your students can turn into converse, inverse and contrapositive statements and identify the truth value.

My original post has similar problems and is still available for purchase. This worksheet was in such demand that I created this new one to share. At the advice of one of my customers I created two versions that have been included in this document. The first page is a simple 1-page worksheet to give to your students where they have to write out the converse, inverse and contrapositive of each statement in their own notebook. If you prefer, I also included a second version with text boxes where the students can fill in their answers. The first page would be easier to copy but the second version would probably be good for your students. A full answer key with explanations is included.

**Disclaimer: You have to decide for your own classroom how "picky" you want to get in your counter-examples. In my class I "outlaw" ridiculous logic. For example if the statement was "If an animal is a pig then it can fly." I would say that is false and not accept the inevitable student answers of "the pig could be on an airplane...the pig could be flung from a catapult, etc." Those examples are funny and worth discussing but they tend to confuse the students when it comes time for testing. If you choose to count those as valid counter-examples the key will not fit your exact class.

If you find this resource helpful I would appreciate any feedback you would be willing to leave. Thanks and happy teaching!
