Two research questions and two null hypotheses were answered and tested at 0.05 significant level respectively. The pretest post test quasi experimental research design was employed. Wechsler Intelligence Scale for Children- Fifth Edition (WISC-V) was used to identify and select a sample of 38 students with dyscalculia. TCAT was used to measure students’ performance in Trigonometry. The KR-21 was used to obtain a reliability index of 0.81.The descriptive statistic and Analysis of Covariance (ANCOVA) were employed for statistical data analysis. The study found that the use of GeoGebra software package improved the performance of dyscalculic students in trigonometry than those who were taught with deductive teaching method. The study also found that there no significant difference between effect of the use of GSP to teach the male and the female dyscalculic students trigonometry over the use of DIM. It was therefore recommended that mathematics teachers should embrace the use of technology (Geogebra software) and other innovative instructional strategies to enhance the academic performance of students with dyscalculia.

Ozofor and Onos (2018) asserted that mathematics affects every area of human activity and as such its teaching in school should be carried out so as to improve the problem solving skills of students. The knowledge of mathematics helps to develop in students the skills of clarity, brevity, accuracy, logical and creative reasoning, precision and certainty in expression and solution to basic and applied problems. The capability of students to develop the afore mentioned skills is focused and directed towards both ability and disability students. This is because the main objective of the secondary school mathematics curriculum is to prepare every student for higher education or a successful work life. There are varied methods of teaching mathematics in the school. The particular method employed by the teacher depends on factors such as the topic to be taught, the ability level of the students, the class size (Anyaozu, 2017). The method of teaching mathematics is broadly classified into the traditional teaching method and the innovative teaching methods. The use of traditional teaching method to teach students mathematics has left us with nothing more than to produce students who dwell in memorization of mathematical facts and processes. The traditional teaching method makes students to understand mathematics concepts instrumentally without knowing the how and why of doing the mathematics process. This may suggest why Saye (2010) opined that traditional teaching method has impacted negatively on students and this has contributed to the poor performance of students in the subject. The method of teaching mathematics changes from time to time and in line with the societal trend and wave. Thus Charles-Ogan and George (2015) opined that the mathematics curriculum should always be revisited by curriculum planners to reform and address the call of trending societal problems. The world is presently functioning at the technological and digital level; an era where technological gadgets are integrated into our daily activities in all sectors. Thus, Ebisine (2013) asserted that re- engineering mathematics education for technological development in Nigeria will be of great benefit to the economy. Eyyam and Yaratan (2014) opined that the use of technology to carry out instruction in mathematics is critical because it allows teachers to provide immediate feedback, individualization of learning opportunities, motivation of students, flexible and collaborative learning.
