Children who have ADHD often have a difficult time waking up in the morning and staying on task throughout the day. They often become overwhelmed when they are given several sets of instructions at the same time and are easily distracted. Using a timer can help them schedule their tasks, estimate how long each task will take, take breaks without being distracted and schedule their most important task for the time of day they are most productive.
A timer is more useful to children who have been diagnosed with ADHD than an alarm clock because it can be set to go off at certain intervals until it is disabled. Children who suffer from ADHD commonly get up when their alarm clock goes off, but return to bed as soon as it is quieted and continue sleeping until much later in the day. Having a timer that sounds every five or ten minutes helps to ensure they will get out of bed and start their day at the right time.
