Possible future puzzles/problems:1) Similar shapes - Rescaling a basic Christmas shape (snowflake, christmas tree) with measurements given, and find the new area. Extension could be two similar snowmen, and finding a new volume.2) I am giving my baby son a mathematical present... He is going to get some wooden blocks (cubes), and each face of each cube is going to be coloured either red or green. How many different blocks are possible? (More of a challenge is 3 colours or 4 colours...)3) How about a Gas,Water,Electricity type problem, where various Christmas characters walk through a snow-filled park from one entrance to a place in the park, but their tracks in the snow are not allowed to cross.
