"The examples show deliberate teaching that results in rich maths learning. They give services and schools working with early learners added insight into how they can extend children's spontaneous learning with responsive and planned teaching.
"We want these stories to be used by others to strengthen maths learning for all our young children."
However, the NZEI Te Riu Roa union said while it supported the initiative, it only highlighted how "the Government got it wrong" when it reduced funding for qualified teaching at kindergarten and early childhood services six years ago.
"The ERO report says international evidence shows that at the age of 10, the quality of early childhood education still influences children's competencies that lead to a successful adulthood, and that mathematical ability is one of the most influential factors," national president Louise Green said.
"This doesn't mean that other skills such creativity and curiosity, as well as social and self-esteem skills are not equally important. But it is very clear that good quality teaching in early childhood is critical."
It was not about pushing kids "into algebra before 5", but there was a "need for a balance between spontaneous child-initiated play and planned mathematical learning", Ms Green said.
"What this highlights is the importance of qualified and skilled teachers who are able to follow the curriculum and engage in and develop rich conversations with children that support their exploration and learning.
"Unfortunately, funding cuts to ECE services and the Government's market-driven approach means that many children will be missing out on quality teaching and learning at a young age."
