Abstract
This research is a descriptive study that aims to describe the role of the solution plan as a scaffolding that helps students to solve mathematical modeling tasks. The subjects in this study were 32 students of grade VIII of Junior High School number 3 Ngaglik. Data collecting using observations and documents. The data collected in this study is in the form of field notes and students^ worksheets. During the learning process, students are given a worksheet about modeling mathematics and equipped with a solution plan, and then the researcher makes observations. The study results found that the solution plan can be used as a scaffolding to support students solve mathematical modeling problems, where the solution plan consists of four stages: understanding tasks, searching mathematics, using mathematics, and explaining results. The solution plan facilitates connecting students^ imagination with the context of the problem and connecting prior knowledge needed to solve mathematical modeling problems through questions or statements that do not directly lead to answers.
