Summer vacation is a time filled with fun, friends... and forgetting everything learned in the classroom. Ensure your son or daughter stays on the straight-and-narrow road to scholastic success this summer with today's deal from Sylvan Learning Center in North Dallas: Pay $99, and your son or daughter in third through sixth grade will enroll in a week-long Fraction Action math camp (a $199 value). This camp meets Monday through Friday from 1 p.m. to 3 p.m. and gives kids all-important instruction in this sometimes-tricky math concept. Pick a week -- June 11 to 15, July 23 to 27, or August 6 to 10 -- and your budding scholar will be immersed in a world of math exercises, games, and formulas to help build brainpower and boost test scores. Come the fall, your son or daughter will be bragging all about summer vacation -- while showing off those steller test results to classmates.
