Lesson details
Key learning points
- Problems can be represented using bar models.
- Problems can be solved using trial and improvement.
- Different strategies work for different problems.
Keywords
Precise - If something is precise, it is exact, accurate and careful about the details.
Infinite - Infinite means without an end. If something is unlimited, you could say it has an infinite number of things.
Common misconception
Pupils resort to trial and improvement each time to solve every problem.
Pupils should look to apply what they know from previous learning and explore the structure of each problem to help them identify how best to solve it. You could come up with a checklist as a class for how best to explore a new problem each time.
