Student’s mathematical communication and abstraction skills were needed in learning mathematics. Another aspect of the student learning process was the need to know and to develop the wisdom of local culture in their daily to lived. This was because students were expected to be a smart generation and still respect their own culture that they will use as life guidance. However, the problem was how to be in still the wisdom of local culture in learning mathematics? Based on these problems, the researcher designed a mathematical learning model that incorporated the wisdom of local culture in mathematics learning. The purpose of this study was to test the Means-Ends Analysis learning model based on the local Cultural Wisdom that had been designed. This learning model was using the wisdom of local culture in mathematics learning. The purpose of this learning model was to improve communication skills and mathematical abstraction skills of students in grade 7. The subjects were Year 7 students of junior high school in the City of Berastagi and Perbaungan. The undertaking, students said that they found it was easier to understand mathematical concepts. Although, the teacher had difficulty in elaborating the problem of mathematical abstraction with the cultural, but the teacher said that the students become easy to communicate their mathematical abilities.

Using Student Activity Sheets (SAS) in learning is one of the teacher's efforts to provide scaffolding to students. This paper is a limited trial in using student activity sheets based on Mean-Ends Analysis (MEA) learning models in the context of Malay culture.The purpose of this study is to analyze the communication and mathematical abstractions ability students' which using SAS in mathematics learning. The study was conducted at a junior high school in Perbaungan, North Sumatra. Subjects in the study were 7th graders. Data were analyzed using descriptive analysis obtained from LAS which worked by students in groups. The results showed mathematical communication ability were in good category, while the ability of students' mathematical abstraction still needed improvement. Thus the student activity sheet based on the MEA learning model can be used as an alternative to improve students' mathematical communication skills
