I think that this topic is one that could lead to a lot of interesting conversations in the classroom. The fact that this holiday takes place during Hispanic Heritage Month also helps to talk about the mixture of Spanish and Native American cultures. It is important to talk about both sides and also have students express their own opinions.
There are three sections of questions.
Video A questions use the video at the top of that website.
*This website has other videos about Columbus that you may want to look at too!
Another activity that might be interesting is to have debates where students are either for or against the celebration of Columbus Day. They would have to prepare their presentations and then afterwards the class could vote based on what was presented to them.
I hope you enjoy these activities as much as I do with my students.
