Ask each team member to try to briefly describe how their neighbour to the right felt during the iteration. Their neighbour confirms or corrects their guess. Once all participants said what they think about how their teammates felt, you get an idea of how connected they are, how the communication is flowing in your team and if people are aware of the feelings expressed, in some way, by others.
This is a round-based activity. In each round you ask the team a question, they write down their answers (gives everyone time to think) and then read them out to the others. Questions proposed for Software Development teams:
When was the last time you were really engaged / animated / productive? What did you do? What had happened? How did it feel?
From an application-/code-perspective: What is the awesomest stuff you've built together? What makes it great?
Of the things you built for this company, which has the most value? Why?
When did you work best with the Product Owner? What was good about it?
When was your collaboration best?
What was your most valuable contribution to the developer community (of this company)? How did you do it?
Leave your modesty at the door: What is the most valuable skill / character trait you contribute to the team? Examples?
What is your team's most important trait? What sets you apart?
('Remember the Future' (#37) works well as the next step.)
Find the source of problems whose origins are hard to pinpoint and lead to endless discussion Source: Henrik Kniberg
Write the problem you want to explore on a sticky note and put it in the middle of a whiteboard. Find out why that is a problem by repeatedly asking 'So what?'. Find out the root causes by repeatedly asking 'Why (does this happen)?' Document your findings by writing more stickies and showing causal relations with arrows. Each sticky can have more than one reason and more than one consequence Vicious circles are usually good starting points for actions. If you can break their bad influence, you can gain a lot.
Get a sense of everyone's position and reach consensus Source: Nick Oostvogels
When the team can't decide between two options, create a big scale (i.e. a long line) on the floor with masking tape. Mark one end as option A) and the other as option B). Team members position themselves on the scale according to their preference for either option. Now tweak the options until one option has a clear majority.

Put sticky notes on the door with the numbers 1 through 5 on them. 1 is the topmost and best, 5 the lowest and worst.When ending the retrospective, ask your participants to put a sticky to the number they feel reflects the session. The sticky can be empty or have a comment or suggestion on it.
