Students' attitude towards mathematics is a factor that affects students' learning activities and mathematics achievement. The purpose of this study is to observe the relationship between the indicators that construct students' attitude towards mathematics in discovery learning using concrete and virtual manipulative. This study uses a quantitative method with a pre-experimental design model. The sample in this study was students of class VIIB as virtual class and VIIC as concrete class at SMP Negeri 31 Semarang. The research sample is given a post-survey after the implementation of discovery learning. SPSS and LISREL are used to analyze the measurement model (CFA). Based on the analysis of goodness of fit statistics, 13 of the 18 parameters state that the causative model of the model in this study is appropriate and compatible to be applied to concrete and virtual classes. In the concrete class, the measurement model shows acceptable reliability and validity. While in the virtual class, the measurement shows that reliability is not fulfilled and there is an invalid indicator, namely anxiety towards mathematics. The average of R 2 value of the indicators in constructing students' attitude towards mathematics in concrete class is 47.8% while the virtual class is only 41.4%. © Published under licence by IOP Publishing Ltd.
