Prayer is a movement and reading that starts from takbiratul ihram and ends by saying greetings followed by the final movement of the prayer. Prayer readings: read the letter al-Fatihah, some letters of the Qur'an, tasbih, tahmid, tasyahud, and greetings. Prayer movements: takbir, standing, bowing, i`tidal, prostration, sitting between two prostrations, and sitting final tasyahud. The research was conducted at Baiturrahman DTA with an action research method using cycles: 1) looking at children's prayer abilities, 2) designing and preparing demonstration methods, 3) practicing prayers using demonstration methods. Data analysis before and after the action is used as the next cycle process. The cycle process ends with the meaning of the data.
