Abstract

 

Mathematics learning materials for multiplication and distribution operations carried out in SD Angkasa Surabaya in class II have not fully involved students' roles optimally. As a result, these activities are affected by students' numeracy ability to be less than optimal. The ability to calculate class II multiplication and division material, obtained data as many as 19 students who had not reached the KKM score of 24 students.

To obtain the results of the study, the research method used was the PTK model Arikunto et al. This research was conducted in two learning cycles which included four stages: Planning, Acting, Observing, Reflecting. Data collection is obtained through teacher and student observation, tests, and documentation.

The delivery of the demonstration method using color straw media and plastic straws can improve students' ability to calculate multiplication and division operations in class II SD Angkasa Surabaya students. This is evidenced by the increase in the observation of teacher and student activities experienced an increase, namely, from observation of the teacher's activity scores increased from 72.5% in the first cycle, to 93.3% in the second cycle. Then the score of student activity from the acquisition of 72% in the first cycle, became 86.6% in the second cycle. In addition, the increase in student counting can be categorized as successful. This is evident from the first cycle and the second cycle, from 66.67% to 91.66%.

Keywords: Calculating Ability, Multiplication and Distribution Operations, Demonstration Methods.
