ABSTRACT: The study aims to determine the effectiveness of Circle Geometry Board (CG-Board) strategy in learning Circle Geometry towards Form Four students’ performance. The Nonequivalent Control Group Pretest-Posttest Quasi Experimental design was used. Fifty-two students from two classes were selected using the cluster probability sampling and were divided equally to control and experimental group. A three-week intervention was conducted using prior knowledge test, pre-test and post-test. The independent t-test was used to describe the students’ performance and the differences between the teaching strategies used. From the analysis, the treatment group students’ performance gained significantly higher than the control group. The study shows that the CG-Board strategy can improve the effectiveness of teaching and facilitating of Circle Geometry among students.
