Proceedings from ICME 15, Topic Study Group 1.2: Teaching and learning of early algebra

Within these proceedings we present the papers submitted to the Early Algebra Topic Study Group (TSG 1.2) of the 15th International Congress of Mathematics Education (ICME) held in Sydney, Australia in July 2024.

The papers presented at TSG 1.2 of ICME 15 represented a deep and broad understanding of early algebra and many interesting and novel findings were shared that prompted robust discussions. Established themes of early algebra, such as the equal sign and functional thinking were the focus of presentations, along with relatively less studied areas related to early algebra, such as cultural relevance and sustainability.
