My students have enjoyed looking at the art history timeline I posted outside my room this year. I really enjoy looking at timelines - being a visual person, it really helps me place historical events in my head.
I have purchased and inherited several timelines from various catalogs and classrooms - every one of them has been so incredibly LONG that is was nearly impossible to use or display it. So I made my own, with each time period on its own sheet so that I can effectively scale down to a particular era (it's not often you need to look at Paleolithic fossils and Pop art at the same time, although it sounds like a fun challenge). So, for example, when we begin an Impressionism lesson, we can look at what came before and what came after in the art world. I really like seeing how art changed after the invention of the modern camera!
I also like including important tidbits that are happening in other parts of the world. Before it comes down from the hall, I am hoping that students might select their favorite time in art history and we will graph the responses.
