"I'll be brutally honest - I thought they could do better. I think give them 6.25m^2 (2.5x2.5) and tell them to make it a bedroom. I will allow for no door entrance, and 3m stud. "

"Plastic Triangle? I thought they were call "Set Squares"? and there are 2 of them. One Isometric (30/60/90?) and one with 60/60/60 angles (the name leaves me).Also you had multiple compasses in a set. Because you couldn't hand draw using your ink pen once you had a pencil circle so doing a final design overlay you had a compass to hold your 0.X ink pen. "
