Objective of the Learning Engagement: Developing students' understanding of surface area through real-life applications, hands-on measurements, and mathematical reasoning. Details of the Learning Engagement: In this engaging activity, students were divided into three groups and given real-life objects in the shape of rectangular and triangular prisms. To begin, they were presented with riddles that required them to identify different 3D shapes and guess the areas of rectangle and triangle. This warm-up helped them recall prior knowledge before diving into the main task. Each group was then assigned two real-life scenarios: one involving painting a rectangular prism-shaped storage box and the other wrapping a Toblerone-shaped gift box, which is a triangular prism. Connecting to their previous unit on scale models, students were encouraged to select similar-looking objects from the provided collection. Some chose rectangular prisms, while others opted for triangular prisms. As they e...

Objective of the Learning Engagement: The Parallel Path: Discovering Triangle Similarity! Identify and apply the AA, SSS, and SAS similarity postulates to determine triangle similarity using angle and side relationships, enhancing reasoning, observation, and problem-solving skills Details of the Learning Engagement: MYP 3 students explored the postulates of similar triangles through hands-on activities. Each group received three pairs of triangles: one to identify AA similarity, another for SSS similarity, and a third for SAS similarity. Using the given indicators for angles and sides, students analyzed and matched the three pairs of similar triangles from a set of six. Students were able to identify similarity quickly by comparing corresponding angles and proportional sides. Those who finished early were challenged to articulate their observations by forming similarity statements in their own words. This activity enhanced critical thinking as students justified their reasoning based o...
