Hi Jan,
I understand your issues with sorting the bricks and I have spend a lot of time figuring out what works for me.
As I do not think that it is a good way to buy new sets all the time for the clients either on the environmental perspective or on the practical perspective (what is the client doing with a lot of lego bricks without a facilitation training anyway?) I opted for a good storing and re-use solution.
I’d like to share it with you.
I own the following sets:
18 Starter Kits (6 of them mixed togehter for Identity work)
1 Identity and Landscape Kit
1 Connections Kit
20 Window Exploration Kits
20 Duck Building Kits
For the 12 remaining Starter Kits I use the Lego Storage Bricks
They work perfectly for the Starter Kits (on kit fits in easily) and are smaller than the airy Starter Kit Box and they even stack togehter. Nice for transportation and the fit the theme.
For the Identity and Connections Kits I use the Lego Education Storage Bins
The set consists of 6 Bins and the orange sorting trays supplied with the Identity and Connections Kits fit in perfectly. So your small parts don’t get mixed up with the bigger parts and everything sits neat and tight.
For the Exploration Kits and Duck Kits I use Zipper Bags
This works fine especially for small introductions and regarding transportation.
What I found out in one of my first sessions is that you always need a lot of bricks from the skills building module.
e.g. I did my first Workshop with the Starter Kits for Skills Building, then packed them away afterwards and thought that the Identity Kit would be sufficient for the rest of the activities. The bricks were sufficient for 4 people and 5 hrs. But I experienced that the participants were used to the Bricks from the Starter Kits and were looking for them in the Identity Building Phase. But the Identity Kit is composed of different bricks. So this was quite hard for them to search for something the got used to and then the didn’t find them.
So I opted for pre-mixing 6 Starter Sets together which will be supplied after the Skills Building Phase in a buffet style on the table.
So I everything is sorted and ready for use and I only need around 30 min. after the Workshops for sorting which is ok.
Hope I could help with it.
