I love this website for both ELLs and native English speaking students, with resources for the classroom as well as home. Here’s a game to practice close reading of poetry: http://www.funenglishgames.com/readinggames/poem.html
And here is a page full of reading, writing, grammar, spelling, and vocab games for all levels: http://www.funenglishgames.com/games.html
Exploring English idioms and oxymorons could be a fun stimulus for a philosophy discussion on language! http://www.funenglishgames.com/funstuff.html
Have fun and have a great day!
