Maths standards in Wales are too low with wide variations in the quality of teaching, according to the schools watchdog.
A report by Estyn inspectors said there was a "concerning decline" in the support and training available for maths teachers and a lack of understanding of the new Curriculum for Wales.
Welsh teenagers' performance in maths slumped in the last Pisa international tests, falling further behind other parts of the UK
Chief inspector of education Owen Evans said too many pupils were not reaching their full potential in the subject.
He said: "Strong mathematics education is fundamental not just to individual futures, but to Wales's future prosperity."
The report said inspectors saw "aspects of effective teaching and leadership of mathematics" but overall "the quality of teaching of mathematics was too variable and pupils' standards in mathematics were too low".
