Mathematics 1.6 Apply geometric reasoning in solving problems
Achievement criteria
On this page: Achievement | Achievement with Merit | Achievement with Excellence
Achievement
- You need to apply geometric reasoning in solving problems.
- This could involve one or more of:
- using a range of appropriate methods when solving problems requiring one or two steps problems (at least three different methods)
- demonstrating knowledge of geometrical concepts and terms
- communicating solutions which would usually require only one or two steps which would usually require only one or two steps.
- Problems are situations that provide opportunities to apply knowledge or understanding of mathematical concepts and methods. The situation will be set in a real-life or mathematical context.
- You need to be familiar with:
- applying angle properties of intersecting and parallel lines and the angle properties of polygons and apply these properties
- recognising when shapes are similar and using proportional reasoning to find an unknown length
- using trigonometric ratios and Pythagoras' Theorem
- deducing and applying the angle properties of circles
- Bearings.
Achievement with merit
- Make sure that you can meet the criteria for achievement
- You need to apply geometric reasoning using relational thinking, in solving problems.
- This could involve one or more of:
- selecting and carrying out a logical sequence of steps
- connecting different concepts and representations
- demonstrating understanding of concepts
- forming and using a model
- relating findings to a context
- communicating thinking using appropriate mathematical statements.
Achievement with excellence
- Make sure that you can meet the criteria for merit
- You need to apply geometric reasoning using extended abstract thinking, in solving problems.
- This could involve one or more of:
- devising a strategy to investigate or solve a problem
- identifying relevant concepts in context
- developing a chain of logical reasoning, or proof
- forming a generalisation
- using correct mathematical statements
- communicating mathematical insight.
