The purpose of this study was to experimentally determine the effects of Explicit Instruction (EI) strategy on the mathematics achievement of pupils with dyscalculia in Federal Capital Territory (FCT) Abuja putting into consideration gender as a variable. Two research questions were articulated and two hypotheses were formulated to guide the study. The study employed a quasi-experimental research design. Specifically, the nonequivalent control group design was used. The population for the study was all the 97 primary three pupils with dyscalculia in Local Education Authority (LEA) primary school Kpeyegie and Local Education Authority (LEA) primary school Garki as identified by the special education unit in AMAC local education authority Federal Capital Territory Abuja. Purposive sampling technique was employed to select the two case schools where the large number of children with dyscalculia would be found, being public inclusive schools. Then the sampled schools were randomly assigned to experimental and the control groups. In the schools selected, two intact classes comprising 20 primary three pupils made up of 11 males and 9 females were used for the study. The instrument for data collection was a 10-item Mathematics Achievement Test (MAT). The instrument was face and content validated. Using Kendall’s Coefficient of Concordance (W), the reliability co-efficient of .88 was obtained for the MAT. Research questions were answered using mean and standard deviation while the hypotheses were tested at 0.05 level of significance using Analysis of Covariance (ANCOVA).The result of the study revealed that: EI has significant effect on the mean achievement scores of pupils with dyscalculia in mathematics; There is significant influence of gender on the mathematics achievement scores of pupils with dyscalculia. Based on the findings some recommendations made among which is that Explicit Instruction should be used in teaching mathematical concepts in primary schools so as to improve pupils’ achievements and participation in the subject.
