The document discusses activities of integration, which are assessments that evaluate students' ability to solve problems by integrating knowledge from a chapter. It provides examples of activities of integration, such as writing a letter inviting teachers to an end-of-year party. It also discusses the components of activities of integration, such as the problem/scenario and expected output. Additionally, it covers how to develop an assessment grid to score activities of integration based on relevance, accuracy, coherence and excellence. Teachers are then instructed to work in groups to create an activity of integration for any S1 topic along with its corresponding assessment grid.
