The present study visions to find out the effect of TIGER method on Interest in Mathematics among IX standard students. This is an experimental study with Pretest-Posttest Equivalent Group Design. A sample of 60 IX standard students were chosen for the study. The investigators applied Mathematical Interest Inventory to assess the Interest level. Data were analyzed using ANCOVA and t-test to determine the performance comparing the mean scores. The findings implied that the experimental group performed better than the control group in post-interest test. It is found that TIGER method had the power to enhance the interest towards mathematics better than their counterparts taught through traditional method.
