摘要:Abstract: The research aimed to develop module of geometry learning with CTL approach in grade 4 and 5 primary school. The geometry learning module consists of two-dimensional figure and three-dimensional shape material. The development model used is divided into three phases as initial investigation, prototype, and assessment. The research instruments used validation sheets and questionnaires. The results showed that the product has reached valid criteria with score 3,65 (high criterion). Based on the validation result, the learning module of geometry with CTL approach for grade 4 and 5 primary school is declared valid and can be applied. Keyword: CTL, geometry, learning module, primary school. Abstrak: Penelitian bertujuan mengembangkan modul pembelajaran geometri dengan pendekatan CTL di kelas IV dan V SD. Modul pembelajaran geometri terdiri dari materi bangun datar dan bangun ruang. Model pengembangan yang digunakan terbagi menjadi tiga fase yaitu investigasi awal, prototipe, dan asesmen. Instrumen penelitian yang digunakan lembar validasi dan angket respon ahli dan praktisi. Hasil penelitian menunjukkan bahwa produk modul pembelajaran geometri dengan pendekatan CTL telah memenuhi kriteria valid dengan ketercapaian validasi modul 3,65 (kriteria tinggi). Berdasarkan hasil validasi tersebut, dapat disimpulkan bahwa modul pembelajaran geometri dengan pendekatan CTL untuk kelas IV dan V SD dinyatakan valid sehingga dapat diterapkan di SD.
