Quiet while learning is important for concentration. Music and especially the TV should stay off.
Background noise from the rest of the family can also be distracting and should be reduced by closing doors.
If concentration wanes, it’s okay to take a short break: fruit or chopped vegetables are a good source of energy for the brain.
Don’t forget to drink – water, juice spritzers or teas keep the brain and body hydrated.
In between, perhaps stand on one leg for as long as you can.
To give the brain a chance to recover, get plenty of sleep at night: 10- to 11-year-olds need around 10.5 hours of sleep, 12- to 13-year-olds 10 hours. Even 14 to 16-year-olds should sleep another 9 hours.
