Abstrak

This study aims to produce a product in the form of smart ladder learning media to find out the feasibility and influence of smart ladder learning media on the numeracy skills of elementary school students. This type of research is Research and Development (R&D) using the Four-D (40) development model. Data collection techniques are in the form of observation, interviews, questionnaires, and tests. The data analysis technique used is descriptive quantitative. The results showed that the smart ladder learning media appropriate for use based on the results of the assessment of the material experts obtaining a score of 94.54% medio experts 96.25% and learning experts 90.90% The results of improving the numeracy skills of students in grade 1 obtained an N- gain value of 0.97 where  N- gain values are included in the "High" category. Thus, smart ladder learning media is feasible to use and cun improve students' mumeracy skills in elementary school arithmetic operations material.
