This study aimed to develop a learning media called Pos Jumlah for addition
materials and to examine its validity and practicality. The research employed a
Research and Development (R&D) method using the ADDIE model, which consists
of analysis, design, development, implementation, and evaluation stages. The
research subjects included first-grade students of SDN 076/I Sungai Buluh, a first
grade teacher, and material and media experts as validators. Data were collected
through expert validation sheets, teacher and student response questionnaires, and
numeracy tests in the form of pretests and posttests.The validation results showed
that the Pos Jumlah learning media achieved an average score of 91%, categorized
as very valid. The results of small-group and large-group trials indicated a very high
level of practicality, as reflected by positive responses from both teachers and
students, with percentages of 91% and 89%, respectively. These findings indicate
that the media is easy to use, engaging, and able to increase student participation
during the learning process.Based on the results, it can be concluded that the Pos
Jumlah learning media is feasible to be used as an alternative instructional medium
in mathematics learning, particularly for addition material in first-grade elementary
school. This media is expected to help students understand addition concepts
concretely and meaningfully, as well as improve their numeracy skills.
