Description:
This CLIL worksheet introduces learners to the geometric concept of angles formed by parallel lines and transversals, supporting both mathematical understanding and English language development.
Learners are required to solve a geometry problem involving angle relationships (corresponding, alternate, supplementary), and then explain their reasoning in English, using provided Speaking Frames. This dual focus develops cognitive and linguistic skills in alignment with CLIL principles.
The task also includes Reflection Questions to support metacognitive awareness and vocabulary development.
This activity aligns with VO Kerndoelen 21 and 26:
Constructing and explaining mathematical arguments
Reasoning about geometric properties of figures
It exemplifies CLIL methodology by:
- Combining content learning (angles in geometry) with language production
- Encouraging academic language use in mathematics (CALP)
- Using scaffolding tools (speaking frames) to support learners at different proficiency levels
