This series is extremely popular with my middle school boys! Loads of images sprinkled with a little text, each book features 13 debates with some factual information. Would it be better to swim like Michael Phelps or run like Usain Bolt? To be a samurai or a medieval knight? My reluctant readers pore over these books, and it's rare to see someone read one without getting someone else involved in the discussion, even if it's just me! While I generally just toss these books on a table of boys and let them noisily debate their choices, this series would be great for teaching argument, too. I've watched students argue over these topics and point to the facts in the book to prove their point. They're getting the fact versus opinion lesson without a lecture! Extend this idea by having pairs of students come up with their own "This or That?" topic, doing research on the two things they're comparing, then debate in front of the class. The speaking and listening portion of the Common Core includes presentation of knowledge and ideas. This would be a fun way to address that standard!
