It can saw on the condition before action (precycle), the score average was 66,84 with learning completeness was 55%. After the action, the score average increases become 83,87 with learning completeness was 74,19% in first cycle and becomes 88,35 with learning completeness was 90,32% in second cycle.The conclusion of this research is the cooperative learning model type Rotating Trio Exchange can improve ability in the addition and substraction operation of integer numbers on IV grade student of Elementary School IV Wonoboyo Wonogiri at academic year 2015/ 2016. Abstrak: Tujuan penelitian ini untuk menigkatkan kemampuan operasi penjumlahan dan pengurangan bilangan bulat melalui model kooperatif tipe Rotating Trio Exchange pada siswa kelas IV SDN IV Wonoboyo Wonogiri tahun ajaran 2015/ 2016.Penelitian ini merupakan penelitian tindakan kelas (PTK) yang dilaksanakan dalam dua siklus. Subjek penelitian adalah siswa dan guru kelas IV SD Negeri IV Wonoboyo Wonogiri.Hasil penelitian tindakan kelas ini menunjukkan adanya penigkatan kemampuan operasi penjumlahan dan pengurangan bilangan bulat secara nyata. Hal ini dapat dilihat dari skor rata-rata kelas nilai tes kemampuan operasi penjumlahan dan pengurangan bilangan bulat sebesar 66,84 dengan presentase ketuntasan kelas sebesar 55% pada pratindakan, meningkat menjadi 83,87dengan presentase ketuntasan kelas sebesar 74,19% pada siklus I dan meningkat lagi manjadi 88,35 dengan presentase ketuntasan kelas sebesar 90,32% pada siklus II.Simpulan penelitian ini adalah model kooperatif tipe Rotating Trio Exchangedapat meningkatkan kemampuan operasi penjumlahan dan pengurangan bilangan bulatpada siswa kelas IV SDN IV Wonoboyo Wonogiri tahun ajaran 2015/ 2016.
