I like to use this activity towards the end of the body parts vocabulary unit. It gives students a chance to be creative and review body parts vocabulary simultaneously!
In this activity students will be creating "arte de monstruo" (monster art). They will be given a crayon and instructions to draw a head (or heads!) ears, eyes, etc. that ultimately make up a complete monster. Each student will contribute to others' monsters while they review body parts, hear instructions in Spanish and do some writing at the conclusion of the activity. Each student will answer 5 basic questions about their monster, writing in Spanish- what is the monster's name, how old is the monster and three others.
My students enjoy this activity each year, and at different levels of fluency. You can adjust to how much your students understand in the language.
I have provided full instructions for the teacher on how to use this activity.
(I would wait to use this activity until my students are familiar enough with the body parts vocabulary that they do not need notes to know what the word means.)
