Before becoming adults, children have to pass three simple tests: recite the whole multiplication table, do their parents' taxes, and successfully save a wedding ring from the bottom of a pool. Help bump your child further up the maturity totem pole with today’s Groupon: for $25, new customers get $60 worth of recreational classes or services at Metroplex Gymnastics & Swim in Allen.

Metroplex Gymnastics & Swim caters to wee ones' experiential education, providing a plethora of classes geared toward having fun, being active, and earning life's merit badges. Certified staff members lead toddlers or school-age children through increasingly challenging gymnastics classes ($50–$140), instructing little legs in tumbling, balance-beaming, and vaulting over prison walls. Adventurous kids can plunge into new hobbies at one of the themed summer camps ($30–$200), with half days of testing out jumping prowess on the trampoline and full weeks of swinging, bending, and swimming on the gym's fun and functional course under the watchful care of the USA Gymnastics–certified instructors.

Meanwhile, bathing babes ready for their aquatic debuts can partake of the two-week swimming-lesson sessions ($142), learning the basics of finless floating and fearless cannonball warfare. For grown-up getaways, the gym also provides a parent's night out ($12/child, 7 p.m.–9:30 p.m.; $20/child, 7 p.m.–11 p.m.), letting little ones rambunctiously frolic while moms and dads catch a movie or streak through their old neighborhood.
