This challenge seemed to give quite a few pupils things to think about and certain decisions to be made.

Lydz and Lilz from Linton Village College said;

There are seven possible groups:

$1$. colour of doors

$2$. colour of roofs

$3$. number of storeys

$4$. amount of windows

$5$. size of the windows

$6$. placing of windows

$7$. size of chimneys

Kali from Burnside Primary of South Australia had a lovely way to show the results - well done for thinking that one out. I like that idea of presenting the answer with a kind of mind-map.
