You report that integrating maths across the curriculum is "tricky". This is only because the curriculum is neatly packaged to make assessment easy, but bears little relation to real life.
Until we develop an education system fully integrated into the community: children active in real projects, that make real, lasting changes to their lives, we don't stand a chance of eliminating disaffection from schools.
We do not need a few examples of integrated mathematics, we need an education system relevant to children's lives, geared to the way they learn, and not determined by arbitrary testing standards.
