Next take out another photo (e.g. your father) and again ask "Who is this?". Elicit and teach the family vocab and stick the photo in one of the squares and write the word (e.g. "father") under the photo. Do for all of the following: father, mother, brother, sister, grandfather, grandmother - you may not have some of these family members, but for the sake of this lesson, use photos of friends, etc., and pretend they are your brother, grandmother, etc.
