ABSTRACT
This study aimed to enhance the problem-solving skills of Grade 7 students using the GAOSA Concept Box, with a population size of 30. A random sampling method, specifically a lottery, was used to select the participants. In the Pretest, 19 students (63%) scored at the poor level, while 11 students (37%) were at the average level in terms of mathematical skills. The researcher implemented the GAOSA Concept Box as a strategic approach to improve learners' problem-solving abilities.
The Posttest results indicated a reduction in the number of students at the poor level, and a significant improvement in their scores, with a two-tailed P value of less than 0.0480. This statistically significant difference suggests that the GAOSA Concept Box is an effective tool for enhancing problem-solving skills. Based on these findings, it is recommended that teachers adopt this strategy to improve learners' problem-solving abilities in mathematics.

CONTEXT AND RATIONALE
The Philippines ranks at the bottom in the latest PISA test on creative thinking, which evaluates 15-year-olds’ skills in mathematics, science, and reading (Chi, 2024). By the time students reach 15, they should already be equipped with 21st-century skills, particularly in problem-solving, to adapt to an ever-changing world and become competent in their studies and careers.
Mathematics is present in everyday life, but for some students, it can be difficult. Challenges often arise when students have gaps in their learning. However, when math is engaging and meaningful, it becomes easier to understand. Addressing these learning gaps requires innovative strategies that enhance both mathematical and reasoning skills.
Many students struggle with word problems because they do not know how to start, affecting their comprehension and problem-solving abilities. A pretest conducted with 30 Grade 7 learners from a school in Claveria West District showed that 19 students scored low on a 20-point word problem test, while 11 performed at average or high levels. This highlights the need for a strategy to improve problem-solving and comprehension skills.
The researcher introduced the GAOSA Concept Box as a solution. GAOSA stands for Given, Asked, Operations, Solution, and Analysis. It guides students through the problem-solving process by filling out these sections, with each part contributing a total score of 10 points.
Using math worksheets with the GAOSA concept can help students master problem-solving. These worksheets encourage learners to explore various mathematical concepts, starting with basic ones and gradually moving to more complex problems. This structured approach helps students understand concepts deeply and apply them in different situations (Itecau, 2022).
21st-century skills can be developed through mathematics. By engaging students in complex mathematical tasks, teachers can foster strategic thinking, which benefits both personal and professional lives (Szabo, 2020).
