Mathematics and Sign Language Learning With a Tangible Game: An Inclusive Approach for DHH and Hearing Children

GIM is a tangible game designed to teach mathematics and Portuguese Sign Language (LGP) to preschool and first-grade children within an inclusive education framework, combining physical memory-style cards with digital sign language videos on a custom interface.

• GIM is a tangible game that combines physical memory-style cards with digital sign language videos to teach mathematics and Portuguese Sign Language (LGP) to preschool and first-grade children in inclusive settings.
• An empirical study tested GIM with 120 children (19 deaf or hard-of-hearing and 101 hearing) across three Portuguese schools from January to April 2022, over 54 sessions, with seven teachers interviewed afterward.
• The authors found stronger knowledge-acquisition effects among deaf and hard-of-hearing children, while awareness and inclusion effects were similar across both groups.
