In Class
Play Family Bingo, which you can have your students design or you can purchase from Teachers Discovery.

Have each student draw and label their árbol geneológico. 

Show students a silly animal “family tree.”  A cat might be married to a dog and have children who are rabbits!   Then have them create their own to show the class.  At the bottom of the tree, have them write out fives sentences about the family members’ relationships.  For example:
    Bowser es el hermano de Trigger.  Lassie es la tía de Bambi etc.

Have your students think about who they would like to invite to a “Reunión Familiar.”  Have them write out a list of at least 8 of these “invitados,” 

mi abuela, Marta
mis primos, Juan y Luis

Have students draw pictures and label their favorite family on TV.

Explain the diminutive to your students, that the diminutive “ito” and “ita”  suffix show affection.  The Teacher’s edition of the Acción Text book, published by Glencoe-McGraw-Hill had this rhyme that I have my students learn by heart.

Mamacita cómprame un regalito
Papacito ayúdame un poco
Hermanito hazme un favorcito
abuelito préstame un dinerito

Here are two other family-related rhymes.

tres, cero, cero, cero
Cerca de la Gran Vía
