Numeracy is a key educational priority, yet its integration across subjects remains inconsistent due to limited clarity, resources, and support. While teachers value numeracy and incorporate it where possible, factors such as school priorities, pedagogical support, and curriculum flexibility influence its implementation. Drawing from a broader study, this paper examines what enables teachers—especially those outside mathematics—to embed numeracy in their practice. Findings highlight the need for targeted professional learning and school-wide strategies to strengthen numeracy teaching across all subject areas.
