Description: I would like to give an overview of our experience with redesigning basic Calculus, Linear Algebra and Probability and Statistics courses over the past three years. Activating students, increasing motivation and ameliorating results of (non-mathematics) students for these subjects are the main goals of the PRojectInnovation Mathematics Education (PRIME). The didactic approach chosen and the material developed, as well as the first results will be presented. Then I would love to collect your ideas on our approach and learn from your project. Some of the developed material is available here: https://www.tudelft.nl/en/eemcs/study/online-education/math-explained/
