Distribute index cards and markers. Set a topic, e.g. one of the following:
How did you feel during the iteration?
What was the most remarkable moment?
What was the biggest problem?
What did you long for?
If the last iteration had been a circus performance, what part did you play? Juggler, funambulist, clown, knife-thrower, ...
Ask the team members to draw their answer. Post all drawings on a whiteboard. For each drawing let people guess what it means, before the artist explains it. Metaphors open new viewpoints and create a shared understanding.
Put up two posters labeled 'proud' and 'sorry'. Team members write down one instance per sticky note. When the time is up have everyone read out their note and post it to the appropriate poster. Start a short conversation e.g. by asking:
Did anything surprise you?
What patterns do you see? What do they mean for you as a team?
Each team member explores one topic in depth in a series of 1:1 talks Source:
Each participant writes down one topic they want to explore, i.e. something they'd like to change. Then form pairs and spread across the room. Each pair discusses both topics and ponders possible actions - 5 minutes per participant (topic) - one after the other. After 10 minutes the pairs break up to form new pairs. Continue until everyone has talked to everyone else. If the group has an odd number of members, the facilitator is part of a pair but the partner gets all 10 minutes for their topic.
Prepare a flip chart with 3 columns titled 'What', 'Who', and 'Due'. Ask one participant after the other, what they want to do to advance the team. Write down the task, agree on a 'done by'-date and let them sign their name. If someone suggests an action for the whole team, the proposer needs to get buy-in (and signatures) from the others.
Let team members appreciate each other and end positively Source:

Start by giving a sincere appreciation of one of the participants. It can be anything they contributed: help to the team or you, a solved problem, ...Then invite others and wait for someone to work up the nerve. Close, when no one has talked for a minute.
