I just recently started to post some of my games and work that I have used in my classroom onto the popular TeachersPayTeachers website.
I'm not going to charge money for games that took me 10-15 minutes to make, what's the point? I do enjoy grabbing freebies off the website, so why should I think other teachers would enjoy the same thing?
This morning, I have already posted our student created Multiplication Search & Find, which was created by one of my students this year! He is very excited that he created this game, just wait until he hears that other teachers may be using it as well!
There is also a adjective card sort game with Comparative and Superlative Adjectives. It is a long but not exhaustive list of the different adjectives (up to eight pages!) that you can laminate, cut out, and put into decks of cards to play!

Have a great day teaching the future!
