We wonder if we know the names of our family members in English and try to make one family tree using this vocabulary. Once we finish it, we explain it to our classmates. 
We complete a worksheet and play a game: Who is…? Which consist on guessing the relationships among different family members. 
We also learn the different names one person can have in his/her family and we do two listenings related with the family members: http://www.carmenlu.com/first/listening/listening/InsideOutBeg/relations2.htm & http://www.carmenlu.com/first/listening/listening/InsideOutBeg/relations1.htm.
