I agree with Expat Mama, Mathletics appeared to be more drill than conceptual learning which is probably the reason our kids find it less useful than interesting than kids who need practise. Good idea about the Singapore Math placements tests.

Ultimately though, it does surprise me that the schools we have had aren't generally interested in finding out what a child's achievement level actually is. Or perhaps I am not surprised as once they know it's harder to make an argument not to act.
