Non-digital games are a tool that can help children to build and improve problem solving skills in early mathematics learning. Teachers need to design a learning activity using non-digital games taken account problem solving skills in the learning activities. However, the application of problemsolving skills in early mathematics learning activities is challenging, as there is no specific reference that can be used as a guide in implementing effective learning activities. The nominal group technique (NGT) approach is used to design the main components and elements of ProSkiND non-digital games framework based on the expert validation. A total of 12 experts were selected to validate the proposed main components and elements of the ProSkiND non-digital game using NGT online workshop. There were five main components with 41 elements were proposed: activity objective, teacher's preparation, teacher's role, children's role, and activity evaluation. In this study, experts are asked to evaluate the ProSkiND non-digital games main components and elements based on the percentage value of agreement. The value of percentage of agreement that exceeds 70% (=70%) is acceptable. The findings in this phase are used to develop main components and elements of the ProSkiND non-digital game framework based on problem solving skills for preschool early mathematics using the interpretive structural modelling (ISM) approach.
