The Yes No game is a fun activity for your youth group or youth ministry meeting. It can be tied in with teaching by reminding us that we need to say "Yes" to God. It also works well with a meeting focused on our Blessed Mother, whose "Fiat" ("let it be done") in answer to the Angel Gabriel at the Annunciation was an affirmation in her complete trust in the Lord.
This icebreaker is part name game and part Duck Duck Goose. There is a lot of handshaking and introductions going on, so this game would be a good youth group activity for a meeting with new members.
You might know that Pope Francis has promoted devotion to Mary "Our Lady Untier of Knots". The Human Knot game is a fun activity to add into a teaching about this devotion. Since it is a cooperative game also makes a fun team building activity.
Shoe Sort is a fun youth group game where people try to match shoes with their owners. It makes a great icebreaker or team building game.
