Avoid micromanaging.
Children including teens can get overly dependent on parents pushing them through their workload each afternoon. Encourage independence from a young age. Help your children prioritize their assignments. Tell them you will check in after a set period of time, like every 15 minutes or when each assignment is complete. Remind them you will look over their homework for accuracy and neatness,but that you won't do it for them.
Build a routine.
Decide that your kids have to finish their homework before they get to play or use electronics. Most children do better when they complete homework earlier in the afternoon (after a 15 to 20 minute break to eat a snack, relax and maybe run around a little to blow off steam). Consider using an incentive system. For example, kids can earn more time to play outside if they complete work correctly within a set time period.
Create a clutter-free work space.
Kids do much better with a neat, quiet work zone. Set up a study nook in your child's bedroom or space that's away from televisions, other electronics, and siblings.
