LOS ANGELES, March 28 (UPI) -- Pop music star Britney Spears is taking math classes so she can help her sons with their homework as they get older and the subject becomes more difficult.
"They go to a really hard school, and this week we had three hours of homework [a night]," Spears told People magazine. "Some of it is hard for me. Next year when [Preston's] in fifth grade, he's going to be doing pre-algebra, and I'm taking classes so I know how to do it!"
Spears went on to say homework is a priority in her family.
"We have a reward system that helps motivate them," she explained. "If they get so many As, they get one toy a month."
