If a biannual series of events occurs biennially, how many times will it occur in 2/5 of a decade?

Filed under: Announcements,Homework — mrweis @ 10:37 pm

Sound confusing?  Just remember that an event that is biannual happens two times a year, while something that occurs biennially happens every other year.  2/5 of a decade is four years.  When you break things down from the circumlocutious title I chose today, you get an event that occurs twice a year, every other year, for a total period of four years, meaning it will occur four times in that time period. This week one of our vocabulary words is biennial, which began a conversation in class today about the difference between biennial and biannual.

In Vocabulary we spent some time going over the words monotonous, trilogy, and biennial.  Tomorrow we will finish up reviewing the final 3 focus words of the week.  While we were talking about the word trilogy, we began a conversation about what a series of stories with other amounts is called.  I asked students to take a look and see if they could find any out tonight.  I did a little research and didn’t come to any really comprehensive information.  I did find some references to groups of four being called both quadrilogies and tetralogies, with tetralogy being considered the more proper term because of its Greek root.  Anyone know about any other terms?  Please share if you do.
