    Phase 1: Giving Aim and Motivating Student

    1. Students pray together

    2. Teacher check student attendance

    3. Motivation :

    Look at cut of newspaper below.

    How many columns in there?

    How many row in there?

    Is the column has same row?

    Where word SMP Negeri 2? Show in row and

    column?

    Where word Paparan? Show in row and column?

    4. To know what is connection that cut of newspaper that given

    with the lesson lets try to solve worksheet.

    2. Teacher divides the students into groups of 4-5 heterogen

    students according lesson score previously

    3. Teacher gives an explanation of the rules for discussion, such

    as:

    a. Use time wisely

    b. Work with the group and do not interfere with other

    groups.

    c. Before ask the Teacher please ask to friend in 1 group

    first.

    d. Worksheet is used to study not only filled and collected

    4. Teacher distribute worksheet on each group and ask for them

    to divide the task in discussions.

    Phase IV. Guiding Group to Work and Learn

    6. Students observe and comprehend the problem in the

    worksheet. (Comprehend)

    7. Students cooperativelywith the friends friends in the group

    about how to solve the proble.

    8. Students remind and apply lesson previously like integer

    operation and linear equation system to help solving the

    problem. (Remind and Apply)

    hanya 20 peserta, biasanya disusun dalam

    lima baris, empat kolom, seperti yang

    disajikan pada gambar disamping.

    Untuk memudahkan pengaturan peserta ujian

    dalam suatu ruangan, pihak sekolah menempatkan siswa dalam ruang ujian dengan pola

    nomor ujian melalui Nomor Induk Siswa (NIS), yang ditempelkan di tempat duduk siswa.

    Misalnya, nomor ujian peserta di ruang A adalah 11, 12, 13, 14, 21, 22, 23, 24, 31, 32, 33, 34,

    lajur ke-2, dan jika nomor ujian peserta adalah 34, artinya posisi peserta tersebut saat ujian

    berada pada baris ke-3 kolom ke-4. Demikian pula, jika nomor peserta ujian adalah 51,

    artinya posisi siswa saat ujian beradaa pada baris ke-5 kolom ke-1.
