Many kids help parents to do chores in the house． They may take out the trash， walk the dog or sweep the floor． In return， some kids get money or other rewards from their parents， such as 20minutes to play computer games．

But some people do not think that kids should get rewards for doing chores． One of them is Jane Smith， a parenting educator and family coach． She believes if kids get rewards， they may think that work isn't worth doing unless you get something in return． For example， kids won't sweep the floor if they see it is dirty． But they will do it if their parents reward them for it．

"Every house is a team effort，" Jane said． "A home is a living space for everyone in the family． It's important for kids to see that we all have a responsibility to keep our home clean．"

Other people hold different opinions． They believe that money or other rewards encourage kids to do more chores． It also teaches them real world lessons． They can learn about how we need to work to make money．

Now， there are also apps that encourage kids to do chores． The apps give kids points and digital （电子的） gifts that can be used either online or in life． With the app ChoreMonster， kids earn digital points after doing chores． Kids can exchange their points for real rewards， such as time to play video games or a trip to the mall． "Our goal is to encourage kids so they can earn rewards，" says Joe Black， founder of ChoreMonster． "Kids need positive （积极的） power to make them do chores．"
