<p>Abstract. This study aims to determine the improvement of children's poetry reading skills with the Contextual Teaching and Learning approach in Class V Students of SDN 2 Nanggulan, District of Cawas, Klaten Regency, Semester I, Academic Year 2018/2019. This Classroom Action Research was conducted in the fifth grade of Nanggulan Elementary School 2 in Cawas District, Klaten Regency with a total of 17 students, consisting of 3 male students and 14 female students. This classroom action research is carried out three cycles in a continuous manner. Each cycle is carried out by planning, implementing, observing, and reflecting to determine the effectiveness of the action. Based on the analysis, it can be<br />concluded as follows: First, based on observations of teacher performance the results of the average score of teacher performance have increased from learning Cycle I for 1.3 Cycle II learning to 2.3, and at Cycle III 2.7. With the criteria of a sufficient limit score is a score of 2 and a score of 3 is good; Second, based on student activity data for three cycles, the average score about student activity experienced an increase from Cycle I learning at 1.2 learning Cycle II to 2.0 and in Cycle III learning to 2.8; Third, based on the results of the assessment of<br />reading children's poetry with the Contextual Teaching and Learning approach, the average score of the test results and assignments has increased from Cycle I learning to 70.89 Cycle II learning to 75.59 and Cycle III learning to 79.71 . Increasing the percentage of classical learning completeness by learning cycle I was 41.18%, learning Cycle II became 58.82%, and learning in Cycle III reached 82.35%. Thus through the Contextual Teaching and Learning approach the ability to read children's poetry in Class V students of SD Negeri 2 Nanggulan, District of Cawas, Klaten Regency, in the first semester of school year 2018/2019 can increase.</p>

This research is motivated by the large number of students who find it difficult to understand the concept of mathematics because generally mathematics is an abstract subject so that the teacher must strive for learning to be concrete by applying learning that can relate the concept to the real life of students. One of the efforts is to apply a contextual teaching and learning approach to present learning that is full of abstract concepts to have a close relationship with students' daily lives. This type of research is a classroom action research conducted in class IV / A SDN 003 Sungai Salak. The number of research subjects was 24 students. The instrument used to analyze students' conceptual understanding used a multiple choice concept comprehension test. The results showed that students' understanding of mathematical concepts in the first cycle was 68.61 with 17 students who completed or 70.83%. In cycle II students' understanding of mathematical concepts increased to 71.11 with classical completeness of 83.33% where as many as 20 students were able to achieve the specified completeness. The conclusion based on the results of this study is that the application of the contextual teaching and learning approach can improve the understanding of the mathematical concepts of grade IV / A students of SDN 003 Sungai Salak on the subject of circumference and area of simple flat shapes.
