Wink Learning provides an extensive set of leveled print workbooks for hands-on learning. We offer 4-5 types of monthly materials, including leveled Korean and Math workbooks, and English storybooks and workbooks, totaling 50-80 types annually and hundreds of types overall. For elementary school students, we provide additional semester-based workbooks. This blended online and offline learning approach ensures that children can master concepts on the device while also getting ample practice on paper. Most importantly, if your child doesn't know a problem in the workbook, they can simply tap a button on the device to get a step-by-step video explanation.
