This is tad ugly right now, but then again this is just a test. (numbers are [inherently] bogus)

*Does 'nigeria-math-1', 'nigeria-math-2', etc, have any advantage over the more explicit page-naming convention 'nigeria_math_k-1'?
** Better to have pages by language and topic.  Math-en, Science-en, &c.
*With this scheme the number of pages to maintain may be a bit oppressive and rather redundant across various countries
** We'll want top-level pages for Math, Science, Arts, &c.  [[User:Sj|Sj]]

Invoked with <nowiki>{{Matrix | country=nigeria}}</nowiki>

Structure:
*Template:Matrix (contains the list of subject areas)
**Template:Matrixrow
***Template:Statusformat (color of numbers)
****cell status page, eg "Nigeria-math-3-status"

{{Matrix | country=nigeria}}
