The method used in this research is R&D research with Borg and Gall development model which is limited to 5 stages, namely potential and problems, finding information, product design, design validation, and design improvement. By involving 3 experts namely 2 material experts and 1 media expert. The results of the study show that animation-based teaching material of social arithmetic are very valid with an average percentage of material experts at 93.5% and 96% of media experts.</em></p>}, number={2}, journal={De Fermat : Jurnal Pendidikan Matematika}, author={Balkist, Pujia Siti and Lukman, Hamidah Suryani and Andriani, Nita}, year={2022}, month={Dec.}, pages={154–159} }
