MYP framing
- Focus ATLs
- Communication: I can show my maths thinking clearly by setting out my work neatly and using maths symbols correctly. I can explain my ideas in different ways, not just give an answer, but also explain why it works.
- Self-Management: I can use my time wisely and practise independently by choosing helpful resources, such as videos and worked examples, to support my learning of mathematics.
- Key concepts
- Connections
- Relationships
- Global context
- Scientific and Technical Innovation – How do we understand the world in which we live? How do humans use integers to describe and interact with the world?
- Community engagement
- Community Building – building classroom community of support and helping each other
- Maths anxiety
- Peer tutoring
