south facing fence

It was time to carry on painting the fence today. I couldn’t help feeling there could be a lot of lesson material here.
The obvious ones..
“If one tin covers 3 panels and we have 9 panels..”
“if the area of one panel is so many squre meters and the paint goes on 3mm thick, how many litres..”

The not so obvious ones.

This could even cover PHSE.

Nature / Geography – “Moss grows on the North side of a tree”. This applies equally to fences.
The picture above is the fence, before painting, south side.
The picture below is the north side.
