A report from the Education Review Office is sounding the alarm about slipping standards in the teaching of maths at primary schools.
ERO says teachers' capability to teach maths is of particular concern. As a result, the review office also has sustained concern about New Zealand's competitiveness in international assessment.
Last year, New Zealand's 13-year-olds recorded their worst-ever results in a major international maths test, and scores for the other age group assessed, 9-year-olds, had also dropped since the last time the test was carried out in 2015.
Kathryn discusses this with Megan Clune, who worked as a primary school teacher for 10 years and is now a teaching fellow at the University of Auckland's Faculty of Education and the president of the Primary Mathematics Association.
