The Nova Scotia government will make Grade 10 math a year-round subject and replace the current semestered version starting next year.
Education Minister Ramona Jennex, who made the announcement Tuesday, said the new course will provide students with 220 hours of in-class mathematics rather than the previous 110 hours.
"No matter what their future plans are, our young people need a strong foundation in math," Jennex said in a statement.
"Parents want their children to develop skills that will help them in everyday life and industry leaders say that math is key."
The move is the latest attempt to improve math results among high school students, who have not scored well in province-wide exams in the last few years.
According to the Department of Education, 56 per cent of students who took the Grade 12 math exam passed in the 2011-12 school year. The year before that, the provincial average was a 52 per cent passing rate.
The new full-year course is set to begin in the fall of 2013.
