Pengembangan Media Circle Number untuk Proses Penalaran Matematika pada Materi Operasi Hitung Bilangan Cacah di Kelas III SD

Development of Circle Number Media for Mathematical Reasoning Process in Material Counting Count Operations in Grade III Elementary School

Pembelajaran yang menyenangkan dan melatih penalaran peserta didik dapat diwujudkan salah satunya melalui penggunaan media permainan teka-teki. Penelitian ini bertujuan untuk mengetahui proses penalaran Matematika melalui media teka-teki angka bernama Circle Number. Penelitian ini berpedoman pada desain penelitian pengembangan ADDIE yang terdiri dari lima tahapan. Hasil penilaian validator terhadap media Circle Number diperoleh skor 92% oleh ahli materi dan dari ahli media diperoleh skor 97,5% dengan kualifikasi keduanya adalah sangat baik. Selain itu, selama proses pembelajaran dengan menggunakan media Circle Number peserta didik melakukan proses penalaran Matematika meliputi proses formulate, employe, interpret and evaluate. Dengan demikian dapat disimpulkan bahwa media Circle Number dapat digunakan dalam pembelajaran Matematika materi operasi hitung bilangan cacah di kelas III SD.

Fun learning and training students' reasoning can be realized one way through the use of puzzle game media. This research aims to find out the process of mathematical reasoning through the media of a number puzzle called Circle Number. This research is guided by the ADDIE development research design which consists of five stages. The results of the validator's assessment of the Circle Number media obtained a score of 92% by the material expert and the media expert obtained a score of 97.5% with both qualifications being very good. In addition, during the learning process using Circle Number media students carry out a Mathematical reasoning process including the process of formulating, employing, interpreting and evaluating. Thus it can be concluded that the Circle Number media can be used in learning Mathematics on whole number arithmetic operations in class III SD.
