Part of learning another language is learning to make the connections between the language and culture you are learning about and how they connect to your own life in the world outside the classroom. There are many instances of the use of the Spanish language or Hispanic cultures all around us.
This presentation asks students to look around their homes and schools to find items that have the Spanish language on them. This helps students become used to keeping an eye out for those connections. I had every level student do this bi-weekly (so the dates are predictable).
