The aim of this research is to determine the validity of LKPD and learning videos on algebraic arithmetic operations based on an Indonesian realistic mathematics education approach. The research method used is development research developed by Tessmer with two stages, namely the preliminary stage (analysis and design) and the formative evaluation stage (self evaluation, expert review, one to one, small group, and field test. In this research the focus is on the formative evaluation, one of which is an expert review.
