Welcome to CC !
Inspiring children to engage in the JOY of learning is a noble pursuit. Children who love to read and are curious about how the world works may enjoy their school years more. Encourage your children to try several different kinds of outside activities, from art to legos to fencing, etc.
Be the family that gets outside and hikes, bikes, and/or camps. Let kids explore the world around them. You might inspire them into geology/astronomy/ecology careers, but if not, you will have bonded over good times.
Time management (especially avoiding proscrastination) is huge. Study skills don’t always come naturally, so setting up a space for doing homework and having a routine can help a struggling student.
Studying is one part of growing up. Learning to interact politely with adults, learning to share well with others, learning to work together, learning to volunteer time for service projects, and caring about others are all things that will make growing up a more pleasant experience.
