Standards of competence: understanding and conduct operations to calculate numbers in problem solving
Basic competencies: get to know the number of fragments and performing fractional numbers
Indicators of results of Study: Gain a fractional decimal

Regular fractions or mixed fractions can be expressed in the form of decimal fractions. Vice versa, decimal fractions can be expressed in the form of regular fractions or mixed fractions. Percent has the meaning of “percent”. Can be written with a 25/100 ratio as 25%, 65/100 as 65%, 10/100 as 10%, 40/100 as 40% and so on.
The resulting decimal number 3 includes a number or Figure 3 repeated. It is said that fractional decimal 0,3333 ... as a recurring decimal. But the decimal 0.35 said decimal no repeats.

Blog short for Weblog which means it is a personal website is always updated contents are continually with links to other website that are considered interesting accompanied with comments on their own.
In education, the digital portfolio system documentation that contains the all kinds of activity results and reflection that can show changes or the development of a State or an individual's potential. Barrett (2004) States that the most important component of a portfolio of digital education is a reflection of learning individually shown some or the entire document portfolio.
Math resources :
a. mathematical communication
b. mathematical reasoning
c. mathematical problem solving
d. mathematical connections
e. positive attitudes toward mathematics

Ebbutt and Straker (1995: 10-63), provides guidelines for teachers of mathematics in an effort to encourage so that the students are enjoying the math at the school, namely:
1.      Mathematics is an activity search patterns and relationships.
2.      Math is creativity that requires imagination, intuition and invention.
3.      Mathematics is a problem solving activity.
4.      Math is a great tool to communicate.
On the other hand, Ebbutt and Straker (1995: 60-75), gave his view that the potential of students could be developed optimally, include :

1.      Student will learn if it gets the MOTIVATION.
2.      Student  studied in its own way.
3.      Student learned independently or through cooperation.
4.      Student needs context and the different situations in his learning.
There are also topic discussion in classroom management include:
1.      Management classes and Educational Paradigms.
2.      Management class: contexts, processes and content.
3.      Classroom Management and Curriculum Mapping.
4.      Characteristics of subjects and students.
5.      Management classes and Learning (CTL) Strategy.
6.      Learning Schemes and Patterns.
7.      Classroom lab and Classroom research.
8.      Managing the classroom and school management.

In order for the math can be taught in a more interesting then Ebbut, S and Straker, A (1995), to advise on the implementation of mathematical learning, through the preparatory phase, the phase of learning, and evaluation stages as follows:
a.      the preparatory stage of teaching
plan learning environment,
planned activities.
b.      stage of learning
develop the role of the teacher,
set the time to whom and when to undertake activities jointly or not with students.
c.       stage of evaluation
observe the activities of students,
evaluate yourself,
judging process, understanding, skills, facts and results,
assess results and monitor the progress of students.

The Iceberg Approach of Learning Fractions in Junior High School : Teachers’ Simulation of Prior to Lesson Study Activities

Pendekatan Iceberg sebagai titik awal urutan belajar yang memberikan pengalaman nyata kepada siswa sehingga mereka terlibat langsung dalam kegiatan matematika. Dalam rangka untuk memanfaatkan pengetahuan matematika siswa, pendekatan ini harus digunakan melalui potensi belajar urutan.
Emilie Naiser A., ​​et al. (2009) menunjukkan bahwa dalam mengajar fraksi-fraksi guru perlu:
·        Pastikan bahwa siswa telah menguasai keterampilan prasyarat untuk tugas-tugas yang harus dipelajari sebagai kegiatan dari presentasi.
·        Perkenalkan instruksi keterampilan dengan demonstrasi singkat dan jelas, misalnya memecahkan beberapa masalah sementara siswa mengamati.
·        Pastikan bahwa contoh pengajaran Anda termasuk kesempatan berlatih yang cukup untuk menghasilkan penguasaan.
·        Pastikan bahwa contoh pengajaran Anda termasuk variasi dari semua jenis masalah untuk menghindari siswa membuat generalisasi yang salah (misalnya, bahwa semua fraksi mewakili bagian dari keseluruhan)
·        Memberikan instruksi sistematis tentang diskriminasi antara jenis masalah berbeda yang
dirancang untuk memungkinkan siswa
agar mengetahui solusi untuk mengerjakan nya
·        Menyediakan praktek sebelum penugaskan
Banyak siswa yang membawa banyak pemahaman informal fraksi untuk instruksi mereka di
matematika, namun seringkali sulit bagi siswa untuk mengintegrasikan instruksi formal dengan
informal
. Tambahan masalah dalam representasi dari angka-angka pecahan meliputi kurangnya pemahaman bahwa fraksi dapat mewakili bagian dari satu set serta bagian dari seluruh unit, dan bahwa fraksi mewakili sejumlah tertentu berukuran sama bagian. Sebagian besar guru mengakui bahwa representasi dari fraksi bisa menjadi tugas yang sangat abstrak dan sulit bagi siswa.
