A natural approach to introducing comparisons! I present this power point to the entire class and let them decide if the sentences are "cierto o falso." Each slide contains a sentence of comparison and a picture of famous people.
A great way to let them see the grammar in action before you break it down.
You can present this to the whole class, or print it as a handout and let them work in teams.
Last slides as them to identify the grammar phrases of comparison.
