Book excerpt: So you think you're smarter than a fifth grader? Well, as many contestants have already discovered on the smash hit TV show hosted by Jeff Foxworthy, you may have either forgotten more than you realize about "the three R's" or simply never learned in the first place! How much do you really know about third grade math? Fourth grade social studies? Fifth grade science? First grade spelling? You may have a high school diploma or a college degree hanging on your wall, but are you smarter than a fifth grader? You'll find out in this book, which includes brain-teasing ten-question quizzes (including million-dollar bonus questions) on information the average eleven-year-old is expected to know—plus there are great bits of fun and fascinating trivia sprinkled throughout. Go ahead—we dare you to prove you're as bright as that gum-chewing kid with the backpack who's waiting on the corner for that yellow bus every morning. School is back in session. And maybe you'll even learn a thing or two that you missed by not paying attention the first time around.
