Last week for something different, I started the class using an app for the iPad called "Akinator". It is similar to "20 Questions". First you think of a person, real or fictional, and then Akinator asks questions for which you must answer Yes/No/Probably/I don't Know/etc. The great thing about the app is that there are many languages in which you can play the game.
When my students walked in, I had Akinator projected on the white board. Of course it caught their attention and they immediately said, "What's that?" and other comments. I told them to choose a person that was real or from a book, or movie, or TV show, or cartoon character or anyone they could think of. We then proceeded with the activity and Akinator proposed the first question in Spanish. Many of the words in the questions were familiar but many times they had to ask me what something meant or they were able to figure it out through context.
After Akinator correctly guessed the characters they had selected, they asked to play again, and again, and again. I limited it to 6 or 7 times, but they wanted to play it the whole class. I wanted to show them that simply by changing the language on games, or apps, you can learn new words in Spanish and increase your vocabulary, and....Have FUN!
If you haven't tried Akinator yet, I strongly recommend it for when you have a few minutes at the end of class that you don't want to waste, or maybe just for an activity to change up the routine that the students will enjoy. It costs $1.99 and worth every penny.
