Bury treasure & draw a ‘real’ map
When we have visitors, one of the games my boys like to organise is a treasure hunt. I have old Tupperware / storage boxes that I don’t mind getting dirty, and I fill one of them with little treasures. This could be easter eggs, chocolate coins, bubble wands, jewellery, anything. The kids (ahem, I mean pirates) go off into the garden (or woods) and bury the treasure chest somewhere in the ground. So we don’t actually lose the treasure, they have to remember to mark the soil somehow, for example with a “secret” rock that will help them recognise it. Then they get to work with a large sheet of paper, making a map that somewhat resembles the setting (i.e. garden chairs, fountain, bush, etc), and then a big X marks the spot where the treasure is. Us grown ups have to follow the map to find the treasure! It’s a drawn-out game that keeps the little kids busy while the parents drink wine. A winning formula.
