Planning overview for Wikijunior:Life[edit]

The following structure is a peg in the ground. It can be added to/deleted from and re-arranged, but please use the discussion page if you want to talk about major restructuring.

I think children should be presented with the material in a child-oriented, rather than a subject-oriented way, thus the major divisions, 'Life today', 'Life in the past', and 'Why are they different?' Following these in a top-down way, anticipating what questions may be in the mind of a bright, inquisitive child, is IMO, the best way to organise the material. My first stab at laying out the territory has not entirely followed this principle, so it is up for plenty of revision. --Barry Desborough 08:52, 4 November 2006 (UTC)
