When considering #CthenC tasks, ask yourself:
- Are there multiple noticings that might be mathematically important?
- Does the task invite multiple shortcuts that leverage mathematical structure?
- Does the task have a ‘long way’ that may involve tedious or lengthy procedures?
- How might I chunk/change the form of/connect this task to math I know to find a structural shortcut?
- Does the task elicit mathematical thinking that can be extrapolated beyond this single problem?
