My situation is different. I'm a Japanese background. Most of my residents use English as a mother tongue. When I conduct "Cross Word Puzzle", "Tongue Twisters" or "Story Telling", sometimes they show me their puzzled faces. I ask "What did I say?" After spelling out the word, they pronounce the word correctly for me. The room turned to an English class room. Most of time they are happy to teach me and I use this as an activity.
I use this technique for other language culture people. So we learn a few different words in French, Dutch, South Africana, Germany, etc.
