How to create pivot table in Laravel 4?

Have you checked out Laravel Migration and Schema Builder Documentation?

Run php artisan migrate:make create_teacher_attendances_table --create --table=teacher_attendances in the CLI to generate the file.

Then edit the file to include something like this up method

public function up()
{
    Schema::create('teacher_attendances', function(Blueprint $table)
    {
        $table->increments('id');
        // Your code here
    });
}

Don't forget about foreign-keys.

You need to execute following command:

php artisan make:migration create_attendance_teacher --table="attendance_teacher"

Note : create_attendance_teacher is taken singular form for the tables attendances & teachers respectively.
As per convention try to create pivot table alphabetical order. Hence we took attendance table before teachers table.

Then, in migration script:

public function up()
{
    Schema::create('teacher_attendances', function(Blueprint $table)
    {
        $table->increments('id');
        $table->integer('attendance_id');//Foreign key from attendances table
        $table->increments('teacher_id');////Foreign key from teachers table
    });
}
