The book presents a quasi-experimental research which utilized Four-Pronged Approach and Four A's Approach as experiential approaches in teaching Mathematics. Two heterogeneous sections in Grade 7 at Wawangpulo National High School. The study administered pretest and posttest to find the cognitive levels of the learners in each group. The attitude of the learners towards Mathematics using Attitude Towards Mathematics Inventory (ATMI) was determined before and after the experiment. The scores in the achievement tests and ATMI were compared and statistical difference was determined using t- test. The relationship of the achievement scores and attitude scores was determined using Pearson-Product Moment Correlation. The learning gains and attitude gains of the learners were also determined after the conduct of the experiment. The book will be useful for teachers of Mathematics, students in the area and researchers.
