Critical thinking skills are one of the important abilities that need to be developed in learning mathematics in elementary school. However, students' critical thinking skills are still relatively low, so learning media that can encourage students to actively analyze and solve problems is needed. This study aims to find out the effectiveness of the Smart Box media in improving the critical thinking skills of fourth-grade students in class IV-A at SDN Sedati Agung Sidoarjo. This study uses a quantitative approach with a pre-experimental research type using a One Group Pretest-Posttest Design. The research subjects consisted of 32 fourth-grade students in class IV-A at SDN Sedati Agung. The data collection was carried out through pretests and posttests designed based on Ennis’s critical thinking indicators. Data analysis was done using the N-Gain Score to find out the improvement in students’ critical thinking skills after using the Smart Box media. The results showed that the students’ average pretest score was 48 and increased to 75.9 on the posttest. The N-Gain analysis scored 0.54 or 54.31%, which falls into the moderate category. These results indicate that the Smart Box media is quite effective in improving the critical thinking skills of fourth-grade students on the topic of whole numbers up to 10,000. Thus, the Smart Box media can be used as an alternative learning tool to enhance students’ critical thinking skills in math lessons at elementary school.
