<![CDATA[The low use of interactive learning media in Indonesian language learning on single sentences in elementary schools causes the learning process to be dominated by conventional methods so that students are less enthusiastic and have difficulty in understanding the material. This study aims to develop Educaplay game-based learning media on single sentences and to determine its level of validity and practicality. This study uses the Research and Development (R&D) method with the ADDIE model which includes the stages of analysis, design, development, implementation, and evaluation. The research subjects were students of grades III B and III C of SDN 4 Made Lamongan. Data were obtained through expert validation sheets, student response questionnaires, and teacher activity observation sheets. The results showed that the Educaplay game learning media obtained a high level of validity with a validation percentage of media experts of 87%, design experts of 82%, and material experts of 85%, so it was declared valid. The level of practicality of the media was classified as very practical with a percentage of student responses in limited trials of 90%, field trials of 94%, teacher activities in limited trials of 85%, and field trials of 90%. The conclusion of the study shows that the Educaplay game learning media on single sentence material meets valid criteria and is very practical so that it is worthy of being used as an alternative Indonesian language learning media to be used in the learning process.
