Three printable versions of the same lesson, each with a data map of the east coast. The last page of each sheet holds the teacher notes (learning intentions, success criteria, big ideas, curriculum links for Australia, the US, England, the IB and others, lesson sequence, differentiation, assessment and a wellbeing note) and the answer guide, and prints separately. All numbers update with the data. Free to use and adapt under CC BY 4.0.
