Loser by Jerry Spinelli

Just like other kids, Zinkoff rides his bike, hopes for snow days, and wants to be like his dad when he grows up. But Zinkoff also raises his hand with all the wrong answers, trips over his own feet, and falls down with laughter over a word like "Jabip." Other kids have their own word to describe him, but Zinkoff is too busy to hear it. He doesn't know he's not like everyone else. And one winter night, Zinkoff's differences show that any name can someday become "hero."
