The purpose of This study to create an effective learning model about organisms categorized to foster motivation and improved students' abilities in the learning process on organism things classification material through the application of the Think Pair and Share type learning model. This research was motivated by the lack of learning models used by teachers, resulting in students not understanding the learning material described and resulting in student learning outcomes are less than the specified minimum completeness criteria. This type of research is classroom action research and is carried out in two learning cycles. The subjects of this research were 32 students. Instruments which is used in this research were observation sheets and questionnaires and also tests. Observation sheets and questionnaires were used to learn the implementation of Think Pair Share learning models and tests to measure the ability of students in categorizing the organism things. Data collection techniques using test and nontest. The data analysis technique used is quantitative descriptive data analysis. The results showed an increase in the observation cycle of learning motivation of the first cycle students as a whole by 67.34% and the observation sheet of the second cycle increased to 88.69%. While the results of students' ability to categorize organism things in the first cycle were 75.26% and the second cycle increased with an average value of student learning outcomes 82.28%.
