Abstract

Mathematics learning at the elementary school level often faces serious obstacles when entering the material of integer arithmetic operations, which is caused by the abstract nature of the concept for students at the concrete operational stage. This community service activity aims to train and improve the ability of integer arithmetic operations in children at the Fadilla Rahma Foundation through the use of slide rule props. The implementation methods used in this service include interactive lectures, demonstrations of tool use, and guided independent exercises. The activity participants consisted of 15 elementary school students who were members of the skilled reading and numeracy classes. The results of this activity show a significant increase in students' knowledge and skills. Before the intervention, students had difficulty visualizing the direction of number movements on negative numbers, but after using the slide rule, students were able to master the calculation steps with an accuracy rate of 90%. The use of slide rule media has proven effective in transforming abstract concepts into concrete ones, making it easier for students to understand the logic of addition and subtraction of integers. In addition to cognitive improvement, this activity also succeeded in awakening students' motivation and self-confidence in working on mathematics problems. The conclusion of this service is that slide rule props are a very representative and effective learning medium to be used at the elementary school level to strengthen children's numeracy foundations. It is recommended for educators to continue integrating physical props in mathematics learning to create a meaningful and enjoyable learning experience.

Abstract

Literacy and speaking skills in early childhood are the primary foundations for their cognitive and socio-emotional development. However, challenges in the field indicate a persistent need for more interactive and enjoyable learning methods to stimulate these abilities. This community service program aims to socialize the storytelling method using picture media for children at the Fadilah Rahma Foundation, covering the Pekan Labuhan and Panah Hijau areas. The implementation methods used in this activity include lecture techniques through creative fairytale narration titled "CICI Ingin Terbang" (CICI Wants to Fly), dialectical question-and-answer sessions to evaluate children's understanding, and demonstration workshops where children create their own original stories and illustrations. The results of the service show an increase in enthusiasm and active involvement of participants during the learning process. Based on observations, most children were able to grasp moral messages and new vocabulary through visual aids, although some participants still required guidance in building self-confidence during presentations. This activity proves that the integration of picture media in storytelling is effective in stimulating imagination and strengthening children's verbal articulation skills. The conclusion of this service emphasizes the importance of multisensory stimulation that involves the senses of sight and hearing synchronously. The main recommendation is the need for regular story-based literacy programs to shape a generation that is wise, creative, and literate from an early age.
