The purpose of developing this instructional material is to produce a valid, practical, and effective reading material. Type of research is research development . The development model is a 4-D model consisting of definitions, design, development, and disseminate. The result of validity test was valid with average value 3.35. The result of observation of the implementation of RPP states that the teaching material is practical with an average value of 90.90. In the effectiveness test stage, the average result obtained 92.33 and as many as 19 students from 20 people total reach Minimum Criteria completeness (KKM). Based on these results, it can be concluded that the reading material oriented cooperative learning model type CIRC in class IV Primary School that has been produced can be declared valid, practical, and effective
