There are 24 students in the class. One-third had their school portraits taken before lunch. After lunch, but before gym class, 10 additional students had their portraits taken. After gym class, how many students have not yet had their picture taken?
How many students were photographed before lunch? ** Before lunch, 24/3=<<24/3=8>>8 students were photographed.
How many students have been photographed by gym class? ** Then 8+10=<<8+10=18>>18 have been photographed by gym class.
How many students remain? ** So 24-18=<<24-18=6>>6 remain.
