Mathematical representative ability is a person's ability to express mathematical ideas, objects, and relationships in various forms of representation, both visually, symbolically, verbally, and contextually. This study aims to analyze the mathematical representative ability of students through counting operations in grade III elementary school in the form of story problems. The method used was descriptive qualitative research with written test instruments to assess cognitive abilities and observation to assess psychomotor skills. The research subjects consisted of five grade III elementary school students, by giving test questions on mathematical reasoning skills, observing students directly in solving and understanding story problems, conducting documentation to obtain accurate data when in the field by classifying students' mathematical representative abilities based on math scores. The results showed that most learners had a very good level of cognitive ability in completing arithmetic operations, but there were some learners who were still lacking in understanding story problems. This finding confirms that the importance of appropriate learning strategies so that learners are not only able to solve problems in the form of operations but also able to understand problems in the form of story problems that are applied in real life.

Da'wah, as explained in the Qur'an, is an effort to invite individuals or groups, as well as the wider community, to embrace and apply Islamic teachings in daily life. This process is carried out in a sustainable and gradual manner, with the aim of internalizing, transmitting, and transforming the messages of Islamic teachings. This da'wah aims to direct humanity to goodness (al-khair), encourage good deeds (al-ma'ruf), and prevent bad actions (mungkar), so that they can achieve happiness in this world and the hereafter. The data used in this study were obtained through the author's observation of the YouTube account Noice (Different But Together). This article focuses on the implementation of da'wah activities on YouTube, as well as the oral and visual expressions used in these activities. The main methods applied by Habib Husein Jafar al-Hadar in his da'wah include emphasizing the themes of love, peace, and tolerance, using language that appeals to the younger generation, collaborating with popular YouTubers among young people, and delivering easy-to-understand da'wah material. Based on these findings, this article concludes that Habib Husein Jafar al-Hadar's da'wah activities have succeeded in attracting the attention of the current generation who often access YouTube, thus increasing the chances of da'wah collaboration to be well received.
