This indicates that the lesson plans were effective in enhancing student learning. 2) Grade 5 students had an average pre-test score of 10.35 and an average post-test score of 16.25 out of a total of 30 points. A paired t-test showed a statistically significant difference at the .05 level, indicating that their learning achievement improved after the intervention. 3) In terms of teamwork skills, the highest mean score was for group participation (𝑥̅ = 4.48), followed by listening to group members’ opinions (𝑥̅ = 4.35), responsibility in group tasks (𝑥̅ = 4.25), and collaborative problem-solving (𝑥̅ = 4.02), respectively. 4) The students' overall satisfaction with learning through the integrated learning unit was at the highest level, with a mean score of 4.58. The highest-rated aspect was learning activities (𝑥̅ = 4.67), followed by perceived benefits (𝑥̅ = 4.62) and content quality (𝑥̅ = 4.45).
