To draw a distinction between Catholic understandings of evangelization and other understandings of evangelizing (like the Ned Flanders caricature), perhaps you could break your ideas into three categories, using the three goals that the US bishops give for evangelization in the United States in their document “Go and make disciples”:

Goal I: To bring about in all Catholics such an enthusiasm for their faith that, in living their faith in Jesus, they freely share it with others.
[Ideas for kids to become more excited and enthused about their own faith]

Goal II: To invite all people in the United States, whatever their social or cultural background, to hear the message of salvation in Jesus Christ so they may come to join us in the fullness of the Catholic faith [Ideas for kids to share their faith with others]

Goal III: To foster gospel values in our society, promoting the dignity of the human person, the importance of the family, and the common good of our society, so that our nation may continue to be transformed by the saving power of Jesus Christ
[Ideas for kids to work for justice, to engage in charity, to engage in service]
