It is good to pray for our parents, they look after us and are very important to us. Think of things to talk to God about your dad. Here are some ideas...
If your dad is not a Christian pray that you and other people will be able to tell him about Jesus.
If your dad is a Christian ask God to help them grow closer to him.
If your dad works, pray that God will help him in his job.
Remember to pray for your dad if he is ill.
