Draw a picture of your family on a piece of paper, card… It can be a family picture or a family tree. Label the members of the family and write down sentences.
E.g Mi padre se llama Juan y tiene 50 años (my dad is called Juan and he is 50 years old). Mi madre se llama Ana y tiene 50 años (My mum is called Ana and she is 50 years old). You can draw as many members of the family as you like.
