This systematic literature review investigates how the concept of time is taught and learned in early mathematics education. While young children are commonly expected to learn how to tell time, this review explores what additional aspects should be emphasised to foster a deeper and more sustainable understanding of time. Using the EBSCO database, 36 relevant articles published up to December 2024 were identified. To cover different aspects related to the teaching and learning of time, peer-reviewed scientific articles as well as practice-based reports were included in the search. A majority of the articles focused on clock reading as an aspect of time. The aspects duration, sequencing, and measurement of time also frequently appeared whereas expressions of time, or cross-disciplinary aspects were seldom mentioned. Drawing on the findings, this review proposes a comprehensive framework outlining key aspects that should be included in early mathematics education to support the teaching and learning of time.
