Abstract
Algebra is quite a difficult subject for most students because there is a transition from arithmetic to algebraic thinking. However, there are several studies showing activities that support algebraic thinking skills that are not always related to formal algebra, therefore exercises to develop algebraic thinking skills can be studied before students learn formal algebra and are even expected to reduce students^ difficulties in understanding formal algebra in junior high school. This study analyzed the algebraic thinking skills of seventh grade junior high school students before being introduced to formal algebra using descriptive method with a qualitative approach. The algebraic thinking ability test instrument questions were given to several students who represented students with high, medium and low mathematical abilities. The results showed that the ability to think algebraically for the initial level was quite good, but in general only showed a little generational activity and did not show transformational activity.
