Abstract.In general, mathematics learning at schools is still a teacher centered, so the students become less active in teaching-learning process. Beside that, the students are also never given a problem-solving work done in groups. It causes the students become passive and just listen to the teacher’s explanation. It makes the students bored and invites difficulties in learning mathematics. It also causes the low score of the student learningachievement. Therefore, it needs a development of learning by applying a problem-solving approach as Polya says about square and rectangular objects to improve the student learning achievement of class VII B in SMP Negeri 10 Jember 2012/2013 academic year.
