This study determines learners understanding of set notations and operations, exploring the challenges and misconceptions that arise when learning these fundamental mathematical concepts. The population under study will comprise of 30 mathematics learners from schools chikani secondary school of Chikankata district making the total of 30 participants. Descrip-tive case study will be used to interview 3(three) mathematics teachers and sampling tech-niques which was employed is a simple random sample. Simple Random sampling was used to sample learners in order to give every learner of the class an equal chance of being included in the sample to be studied. A mathematical test MAT 4024/1/2 will be used to get data from learners. The findings of the study will reveal the learners understanding in the mathematical set notations and operations to determine whether pupils could barely understand the mean-ing of set notations and operations used in the teaching and learning of sets in secondary schools. The results will highlight the need for targeted Instructional Strategies to support learners understanding of set notation and operations, providing insights into the design of effective learning materials and activities.
