This prompt is designed to get departments thinking about where in the curriculum students must create and solve linear equations. Can you think of any other concepts this connects to? Are you teaching creating linear equations explicitly? Do the department have a common approach to solving linear equations?
Further questions:
- For cell 3 and 5, are you explicitly teaching cross multiplication as a trick, or is it something students develop themselves? What the the issues with cross multiplication?
See this twitter thread started by @DrFrostMaths on cross multiplication.
