This study aims to analyze the implementation of the Think Pair Share (TPS) learning model in improving problem solving skills in fractional materials for grade V students at SD Negeri 3 Mantingan. The background of this research is the low ability of students to solve fractional problems, mainly due to procedural misconceptions and lack of opportunities to discuss and construct understanding collaboratively. The method used is the Kemmis and McTaggart model Class Action Research (PTK), which consists of four stages: planning, action, observation, and reflection. The research was conducted in one cycle, involving 28 students as subjects. Data collection was carried out through evaluation tests (pre-cycle and cycle I) as well as observation of student learning activities. The results of the study showed a significant increase in problem solving ability. The average score of students increased from 36.43 in the pre-cycle to 93.21 in the first cycle, with a t-test of 25.18 and a p< value of 0.001, indicating a high significance. Learning completeness increased from 0% to 100%. The TPS model has been proven to be able to overcome misconceptions, especially through the peer scaffolding process in the "pair" stage, which helps students in identifying variables and choosing the right calculation operations. In addition, there was an increase in students' collaborative skills in terms of expressing opinions and asking questions, with an achievement range between 68% to 75%. The main obstacles faced in the implementation of polling stations are the management of discussion time and class noise. However, this was successfully overcome through the use of timers and Student Worksheets (LKPD) equipped with scaffolding questions. It can be concluded that the TPS model is an innovative and effective approach in improving mathematical problem solving skills contextually, in line with the principles of the Independent Curriculum.

This study aims to improve the understanding of third grade elementary school students on time measurement material through the application of the Numbered Heads Together (NHT) learning model with board game media. The main problem in conventional learning is the low active involvement of students and the difficulty in understanding the concept of time concretely. This research is a Classroom Action Research (PTK) conducted in two cycles using the Kemmis and McTaggart model. The research subjects were 23 third grade students of SDN 1 Langon, Jepara. Data collection techniques included observation, interviews, tests, and documentation. The results showed a significant increase in student understanding, which was marked by an increase in the average score from 65.3 in the pre-cycle to 85.3 in cycle I, as well as an increase in learning completeness from 40% to 68%. Students were more active in discussions, motivated, and able to explain the concept of time independently. The NHT and board game model creates a collaborative and fun learning atmosphere and supports students' cognitive, social and emotional development. These results prove that educational game-based learning strategies are effective in improving the understanding of abstract mathematical concepts, especially time measurement.
