Here are a handful of the legions of online resources for parents who need a bit of assistance re-familiarizing themselves with their child’s homework subjects:* Discovery Education (discoveryeducation.com/parents) offers free family resources such as by-subject homework help as well as access to WebMath, which offers guided, step-by-step instruction to properly solve math problems.* Brainfuse (brainfuse.com) provides homework assistance and one-to-one tutoring for students throughout their academic careers, from kindergarten through high school. Brainfuse is a subscription service, but members of the Chattanooga Public Library can access it for free through chattlibrary.org/resources-homework.* PBS LearningMedia (pbslearningmedia.org) compiles more than 100,000 digital learning resources for elementary, middle and high school and university students.
