I use this presentation to give my students the chance to practice the verb to be. I show them a picture and I ask them to use the right form of verb to be to make a correct sentence.
Ex: I show them a picture of a boy and they need to provide a correct sentence: I am a boy_ He is a boy._ Tom is a boy....
PS: Some pictures are related to a Moroccan context, so you may need to replace them with others that are more appealing to your students.
