My sister's 8th birthday is coming up next week, so I'm planning a surprise party.

The 8th graders organized a fundraiser to buy new books for the school library.

My sister is in 8th grade and is preparing for the regional science fair.

The precedent set by the 8th Cir. in that case continues to influence district court rulings across the region.

The 8th grader stayed late after school to finish the science project.
