Years ago, using Tinker Toys, I would read from a list as to how an object was to be constructed, with commands such as,
– take a round, 8-hole wheel and put a 4-inch blue stick into the center hole
– on 4 of the holes in the rim of that wheel, put 2-inch yellow sticks.
– on the other 4 holes in the rim of that wheel, put 1-inch green sticks
– on the end of the 4-incl blue stick, place another round 8-hole wheel so that the blue stick goes into one of the holes on the rim.
and so forth. Maybe 20 steps, You could also ask for a volunteer and then have them read the instructions. You can also add a time limit, no-talking rules or whatever.
Needless to say, the results vary!
You could certainly read to the group a set of instructions about how to assemble the duck with LEGO and you could play games with availability of different pieces across tabletops, having missing pieces you forgot to distribute, etc.
And you could combine this with Rodrigo and Lise’s ideas.
The KEY is to generate a debriefable outcome, one that matches your session goals.
