Handout that was developed is the handout based onrealistic approach contain of description of material, exercise and evaluation. Thisstudy aims to determine how the validity and practicality o handout based on arealistic approach for material o algebraic operations at SMPN 20 Padang. Thisresearch is development research. The procedure development of this model isused 4-D model that consists of 4 stages define, design, develop taht proposed byThiagarajan et al in Trianto (2012: 93). This study is limited to the stage ofdevelop, that is validity and practicality. The handout were validated by 4validators categorized as valid with the value 3,35 and categorized as practical bythe teacher with percentage 87,01%. Then, by the students categorized as verypractical with percentage 85, 40%. From this research, it is produced a productnamely handout based on a realistic approach for the materials of algabraicoperations in mathe amtics learning grade VIII at SMPN 20 Padang that valid andcan be used.]]>
