This article examines the development of mathematics learning design using the Dick and Carey model in material simplifying algebra forms for class VII SMPN 217 Jakarta. Learning design refers to the process of planning and developing effective learning structures, strategies and activities to achieve desired learning goals. The purpose of writing this article is to explain the steps for developing learning design by applying the Dick and Carey model in designing mathematics learning on material that simplifies algebraic forms. The results of developing designs using the Dick and Carey model in developing mathematics learning designs can help teachers in designing and implementing learning.

The research method used in this research is Research and Development. The subjects in this study consisted of validation subjects consisting of material and media validators and test subjects consisting of 23 grade VII junior high school students. The research was conducted at SMP Negeri 10 Sungai Kakap. The instruments used in the study consisted of expert validation sheets, respondent questionnaires, and tests of mathematical understanding abilities. The purpose of this study was to determine the process of developing an Android-based math educational game using software construct 2 on mathematical abilities. The results of the study are as follows: The level of feasibility of an Android-based math education game using software construct 2 on the ability to understand the results obtained is 88.66% with very feasible criteria. The level of attractiveness of an Android-based math education game using software construct 2 on the ability to understand the results obtained is 88.19% with very interesting criteria. Improved mathematical understanding skills after the application of Android-based math education games. There is an increase From the calculation results obtained tcount> ttable = 8.85987> 1.71714, thus Ho is rejected Ha accepted.
