Abstract

This research aims to develop mathematics teaching materials in the form of lesson plans and teaching aids. This type of research is development research using the ADDIE model which consists of the stages of Analysis, Design, Development, Implementation, Evaluation. In this study, researchers studied up to the Development stage. In testing lesson plan teaching materials and teaching aids, a validation sheet is used which is filled in by the validator. The average validation results for RPP teaching materials and teaching aids obtained a percentage of seventy nine point twelve percent. So the development of the fractional pizza props is included in the category of being quite valid and effective for use in the learning process but requires minor revisions to the product. Based on the results of this research, it can be concluded that the development of mathematics learning using fractional pizza props in fractional number material for junior high school students has been tested for its validity.
