What would be the right move to handle a supervisor that favors coworkers and singles you out?

My supervisor keeps singling me out at work. It’s like everyone in my crew but me are in this work circle and I’m just hanging alone. I’m always in the dark when it comes to a group thing that I’m supposed to know for work. It’s starting to get old now.
I do what I’m told and I try to do it best. I show up to work every day on time. I keep my mouth shut at work. I like what I do for work but I feel I’m stuck doing the same thing over and over again while others rise up and learn different skills.
