This study aims to identify the numeracy ability of grade I students of Madrasah Ibtidaiyah Based on Cognitive Level. The research method used is quantitative with a descriptive approach. The population used by all students of MIN 4 Medan. Sampling from the population used the Issac Michael technique which obtained a result of 249 from the entire population. Furthermore, samples were taken using cluster sampling which was specifically for classes I, A and I B, a total of 56. The test instrument is in the form of an objective description of the "filling" and the results are in the form of scores. The data analysis in this study is a descriptive quantitative data analysis. The results showed the numeracy ability of students in class I MIN 4 Medan, namely: 1) the level of remembering for the "high" category was 37 students or 75.51%; for the "medium" category: there are 4 students or 8.16%; and the "low" category there are 8 students or 16.32%. 2) the level of understanding for the "high" category was 28 students or 57.41%; the "medium" category has 16 students or 32.65%; and the "low" category there are 5 students or 10.20%. 3) the application rate for the "high" category was 18 students or 36.73%; the "medium" category has 29 students or 59.18%; and the "low" category has 2 students or 4.08%. The implication in this study is to increase the practice of contextual questions and carry out game-based learning.

This research aims to find out how to develop animated video learning media to improve the mathematical problem solving abilities of class VI students. This research is based on several problems, namely students who do not understand the discussion of learning material because mathematics is considered boring and it is difficult to memorize formulas. This made students unable to solve problems in the learning process. This research used research method and development using 4D research model. The sample of this research consisted of 25 students, with the first step not using animated videos and the second step using animated videos. The research instruments used in this research were tests (essays) and questionnaires. The research results showed that the feasibility level was 92% in the "very valid" category, the practicality level was 92% in the "very practical" category, and the effectiveness level was 88.52% in the "effective" category. These results can also be seen from the pretest with an average value of 34 and posttest with an average value of 92, so the average N-Gain Score was 88.52%. So, it can be concluded that the development of animated video learning media can improve the Mathematical problem solving abilities of 6th Grade of Elementary School students.
