There were loads of people this week. There must have been over 20 in total including the little ones. It was quite overwhelming and I think an important lesson in how I respond to the sessions and difficulties faced by explorers.
The first issue was that there were a lot of newer explorers and parents who I wanted to get the chance to talk to or induct and that wasn't possible but there were some positive things to take from this.

It was a real buzz of activity. A lot of the explorers came up with discoveries, solved puzzles and worked through activities independently. In some cases, the parents got to work with their children in a new way that seemed to be a useful thing for them. It was just like a club too. There were lots of interactions, mostly those that I didn't make happen but a few of those I introduced also worked well together. There were also good examples of people working independently. R2D was a great example of both. She went around trying as many of the activities on the sheet as she could and occasionally working with others.

The range of activities and problems associated with the activities were not so well thought through but they provided some good opportunities for the skills and habits that I'm looking to promote. They were not self access enough to work for newer explorers unfortunately but there need to be some activities like that. The plan for a map could be a suggested route through the puzzles. There could be a competitive route and a collaboration route and then each activity could have instructions about how to play competitively or collaboratively or if it just lends itself to one or the other. This way explorers could come up with other ways to do the task and this might help them see that aspect of the explorer way, to come up with new ways to play old games.

A meeting game would have been good once everyone had their codes. It could be a challenge for new and more experienced explorers to find the real names of some of the codes for example. Or I could mix up a few of the characters and have that as a group challenge to see if they can add something towards the discovery of the key people for that week.
The parents and explorers all got together and helped to tidy up. I don't know what I would have done without that.
Key takeaways
Some kids will form groups naturally, others won't and will need help. This should be a key part to the session
I should look to find ways to help people (parents and children) get through the sessions without my help.
I should think of some parings that I think would work from the beginning and set them a collaborative puzzle to start things off (I would need to be there early for that kind of thing to happen of course)
Set up induction events (once a month perhaps)
Continue work on the self access nature of activities
Continue coming up with ways to get feedback from everyone.
Find a way to introduce a plenary activity that doesn't involve too much talking or listening but gets explorers to say draw a picture of something important or talk to one person to tell them about an activity (think, pair share for example)
