It's a very simple activity to encourage your students to use the Present Tenses. You can divide them into small groups or ask them to work in pairs.
Then, you can make copies of the following picture or project this on a white board.
Now, they start describing the photo and asnwer questions such as: what are they doing?, what are they wearing? As a teacher, you can walk around and help them with the vocabulary, pronunciation, ... Let's SPEAK UP!
Learning English is alsways FUN!!!;)
