Kegiatan Pengabdian kepada Masyarakat (PKM) ini bertujuan membangun kemampuan computational thinking peserta didik melalui eksplorasi bentuk dan pola geometri, serta mengetahui peningkatan kemampuan tersebut setelah mengikuti pelatihan. Kegiatan dilaksanakan di Panti Asuhan Wisma Karya Bakti, Bojongsari, Depok, dengan sasaran 11 peserta didik setingkat kelas X, menggunakan pendekatan pelatihan partisipatif dan pembelajaran berbasis eksplorasi (exploration-based learning) yang terdiri atas tahap persiapan, pelaksanaan (pretest, penyampaian materi, eksplorasi, diskusi, penyelesaian masalah), dan evaluasi (posttest, observasi, refleksi). Hasil kegiatan menunjukkan peningkatan rata-rata nilai peserta dari 24,55 (pretest) menjadi 64,55 (posttest), dengan nilai N-Gain rata-rata sebesar 0,53 yang tergolong kategori sedang; secara individual, 4 peserta mencapai kategori tinggi, 4 peserta kategori sedang, dan 3 peserta kategori rendah. Peserta juga menunjukkan keterlibatan aktif dalam mengenali pola (pattern recognition), memecah masalah (decomposition), melakukan abstraksi (abstraction), dan menyusun langkah penyelesaian secara sistematis (algorithmic thinking). Kegiatan ini terbukti dapat menjadi alternatif pembelajaran matematika yang lebih interaktif dan bermakna dalam mendukung penguatan computational thinking peserta didik.
