Evaluation is an important activity carried out by educators in the learning process. By evaluating educators, they can improve their competence in class management both in choosing learning methods, media, teaching materials, and so on which can motivate students to learn. In addition, with evaluation educators can find out the level of success of their students. Therefore educators must carry out evaluation activities properly. However, in reality there are still many educators who have not carried out the evaluation process properly, especially in elementary schools. One of the causes is the lack of knowledge that educators have about the evaluation itself and it is often found that teachers manipulate student grades, as a result of manipulating grades will have a bad impact on their students. So that knowledge is needed about the concept, the role of evaluation to the procedures for carrying out evaluations in order to obtain evaluation results that can describe the real state of students.

Individual differences that need to be considered in the implementation of classroom teaching are factors related to the readiness of children to receive teaching because these differences will determine the education system as a whole. These differences with other individual approach as well, but it is still realized that education is not solely aimed at developing individuals as individuals, but also in relation to the varied patterns of community life. The factors that influence individual differences are self-concept, the anxiety experienced by students, learning motivation.

Students with learning difficulties in mathematics often make mistakes in solving story problems on fractional material. This research uses descriptive qualitative. The purpose of this study was to determine the types of learning difficulties in mathematics experienced by students, the factors that influence learning difficulties, and to reveal the efforts that can be made to overcome the difficulties in learning mathematics in grade IV Pakujaya 02 State Elementary School. Data collection techniques were observation and interviews. . Based on data analysis and discussion, students experienced errors, namely: 1. Understanding the problem, namely errors in interpreting language and making mathematical models. The reason is incomplete/wrong reasoning and low student ability. 2. Planning for problem solving is an error in connecting one concept with another concept. The cause of this error is the humanistic thinking of students. 3. Implement problem solving planning, namely errors in implementing incorrect formulas. Errors in this aspect are caused by incomplete or incorrect reasoning and students' humanistic thinking.
