The document describes a math CLIL lesson plan on angles for 4th grade students. The 60-minute lesson includes brainstorming what students know about angles, completing manipulative activities to identify angles and classify them by type, looking for real-world examples of angles, and creating an artistic composition with angles. The goal is for students to learn angle vocabulary in English while reinforcing math concepts about angles. The teacher reflects that students showed great engagement and effort communicating in English, though not all activities could be completed in the time given.
