Achievement Criteria

Achievement
• Apply algebraic procedures in solving problems.

Achievement with Merit
• Apply algebraic procedures, using relational thinking, in solving problems.

Achievement with Excellence
• Apply algebraic procedures, using extended abstract thinking, in solving problems.

____________________

  1. Apply algebraic procedures involves:
  • selecting and using procedures in solving problems
  • demonstrating knowledge of algebraic concepts and terms
  • ·communicating solutions using appropriate mathematical symbols.

Relational thinking involves 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;
    and also relating findings to a context, or communicating thinking using appropriate mathematical statements.

Extended abstract thinking involves 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;
    and also using correct mathematical statements, or communicating mathematical insight.

2 . Problems are situations that provide opportunities to apply knowledge or understanding of mathematical concepts and procedures and methods.  The situation will be set in a real-life or mathematical context.

3. Students need to be familiar with procedures related to:
  • factorising
  • expanding
  • simplifying algebraic expressions involving exponents, such as or 
  • substituting values into formulae
  • manipulating and simplifying expressions such as or 
  • rearranging formulae such as  or  
  • solving linear equations or inequations such as 5x + 12 = 3 - 2x  or 3(x - 2) < 7
  • solving quadratic equations such as (8x + 3)(x - 6) = 0, x2 + 5x – 6 = 0, 3x2 =10x -8 (completing the square and the quadratic formula are not required)
  • solving simple equations involving exponents such as x3 = 8, 5x=125
  • solving pairs of simultaneous linear equations with two unknowns.
