This is a presentation I created to teach adjectives to elementary students. Explain that their character depends on the colour they like, and now they may find out a lot about thair friends or parents. It helps to revise qualities and understand themselves deeper. You may pracrtise constructions like "He is clever and kind". What kind people do you know? Later you may discuss qualities of a perfect friend or ask them to describe someone. For dialogues it may be possible to introduce mingling activity.
