Hank thought that getting through summer school to get to the fifth grade would be hard enough, but little did he know that it would get worse! Everyone in the fifth grade is starting to focus on a sport—and they’re really good. Everyone, that is, except Hank. When Papa Pete suggests that Hank take up Ping-Pong, he decides to give it a try but keeps it top secret, as he thinks the other kids will tease him about it not being a "real" sport. Hank is so good that he manages to Ping-Pong his way to the championship! But when he finds out the contest is being held at "Nick the Tick" McKelty’s family bowling alley, will he risk being the laughingstock of the fifth grade?

With the help of his grandfather, underachieving fifth-grader Hank Zipzer finally discovers that he is good at ping-pong, but he is afraid to tell his classmates for fear of being ridiculed.

Fourth-graders Hank, Ashley, and Frankie are excitedly preparing for a magic show at the Rock 'N Bowl when Hank's creative alternative to an English essay lands him in detention and grounded the week of the show.

The pressure is on when Hank Zipzer is chosen as pitcher for the softball team at Public School 87's annual Olympiad, the most anticipated day of the school year.

It’s graduation time for Hank Zipzer and all his friends— time to move on from PS 87 to middle school. Trouble is, there are tests Hank has to pass to get into the same middle schools as his friends, and his learning differences might get in the way. Luckily, a life-altering audition at a performing arts middle school helps him find his true path.

Hank tries to keep his new favourite sport, ping-pong, a secret from his family and friends.

One afternoon, Hank overhears his mom and Frankie's mom talking about having a baby. Having a baby!? It must be Frankie's mom that they're talking about! Frankie will go crazy when he hears about this! Hank worries about how to break the news to his best friend, until he finds out that it's his own mother who is pregnant! How could she do this to him? One annoying sibling is enough. Hank definitely did not order this baby!
