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
Systematically - Working systematically means to solve a problem in an ordered and methodical way to ensure all outcomes are recorded.
Efficient - To solve something efficiently means to solve a problem quickly whilst also maintaining accuracy.
Common misconception
Pupils opt for a trial and improvement approach, without working systematically either.
Encourage pupils to identify the structure of the problem and represent the maths in a way that makes sense for them. You can then take their representations of the maths and refine them so they are more efficient.
