Abstract

General Background Mathematics learning in elementary schools plays a crucial role in developing logical thinking and problem-solving skills; however, it is often dominated by procedural exercises. Specific Background In the context of learning the greatest common factor (FPB) in class V MI Ma’arif NU Sukolilo, teaching practices remain focused on lectures and written tasks, limiting students’ conceptual understanding and numeracy literacy. Knowledge Gap This condition indicates a gap between concept-oriented mathematics learning and the conventional instructional practices that do not sufficiently engage students in contextual and meaningful experiences. Aims This study aims to describe the implementation of the FPB Fun Day co-curricular program and analyze its role in improving numeracy skills, FPB conceptual understanding, and numeracy literacy. Results Using a descriptive qualitative approach, the findings reveal that FPB Fun Day is implemented through contextual activities such as distributing objects evenly, increasing student participation, conceptual comprehension, and the ability to interpret and communicate mathematical problems. Students with higher abilities tend to apply conventional strategies, while those with difficulties benefit more from contextual approaches. Novelty The study introduces a co-curricular, experience-based learning model integrating FPB concepts with numeracy literacy through real-life activities beyond classroom routines. Implications The findings suggest that contextual and activity-based learning can serve as an alternative strategy for strengthening conceptual understanding and numeracy literacy, supported by teacher creativity, student engagement, and institutional support despite challenges in time management and varying student abilities. Highlights • Contextual activities using real objects support deeper mathematical reasoning• Learners with lower abilities gain clearer understanding through visual practice• Collaborative tasks promote active participation and logical problem solving Keywords FPB Fun Day; Mathematics Learning; Numeracy Literacy; Conceptual Understanding; Contextual Learning

Abstract

General Background: Creativity is a fundamental 21st-century skill for elementary students, yet it remains relatively low due to teacher-centered learning practices. Specific Background: Observations in Grade 3 at SD Negeri 1 Tatura revealed limited student innovation, low confidence, and minimal active participation in problem-solving activities. Knowledge Gap: Previous studies largely focused on upper-grade students, used classroom action research, and rarely examined detailed subdimensions of creativity or specific school contexts. Aims: This study aims to examine the increase in student creativity through the implementation of the Problem Based Learning (PBL) model using a quasi-experimental design with pretest-posttest control groups. Results: Findings show a significant difference between experimental and control groups (sig. 0.007 < 0.05), with higher posttest mean scores in the experimental class (49.42) than the control class (38.08). However, N-gain results indicate low overall improvement (0.2152) and uneven development across creativity indicators, with fluency categorized as high (0.7368), flexibility and elaboration as moderate (0.5538; 0.4985), and originality as low (0.1955). Novelty: This study applies a quantitative experimental approach focusing on Grade 3 students and analyzes creativity through detailed subdimensions within a specific school context. Implications: PBL supports increased student creativity but requires optimization, continuous guidance, and strategic implementation to ensure balanced development across all creativity indicators. Highlights• Significant difference found between experimental and control group outcomes• Highest gain observed in idea generation compared to other dimensions• Uneven development identified across multiple creativity indicators KeywordsProblem Based Learning; Student Creativity; Primary School; Quasi Experimental Design; Creative Thinking
