  This study aims to improve mathematics learning results in the second grade
of elementary school, especially the matter of fractions. The background of the
research is the low learning outcomes achieved by students due to the learning
carried out does not pay attention to the level of student development. This
research was classroom action research. The research subjects were 23 students.
The data collection instrument used the observation sheet and documentation.
Quantitative data analysis techniques with descriptive statistics were used in
this study to compare conditions before and after the action was carried out.
The results showed an increase in mathematics learning outcomes in the subject
of fractions. Student motivation shown in the implementation of learning in the
second cycle reached 3.91 (high category) with N-Gain reaching 46.49%. The
level of completeness has reached 100%. The average value obtained by students
in the second cycle was 80.2 and N-Gain reached 34.16%. This increase was due
to the learning carried out using fractional blocks. These results illustrate
that the use of fractional blocks can improve mathematics learning outcomes,
especially in the subject of fractions.
