no explanation - a single simple response required (orally, or in writing)

  • no explanation - a simple response required (orally, or in writing)
  • simple explanation of a (level 1 or 2) mathematical process required (orally, or in writing)
  • explanation of a (level 3) mathematical process required (orally, or in writing)
  • complex, abstract and generative reasoning or explanation required
Compute
  • a simple arithmetical operation (+, -, x, ÷) with whole numbers or money
  • calculating common fraction, decimal fraction and percentages of values
  • using common rates (e.g. $/lb.); time calculations; etc
  • changing between common equivalent fraction, decimal percent values, including for measurements e.g. ¼ kg = 0.250kg
  • more complex applications the normal arithmetical operations such as with fractions and more complex rates, ratios, decimals, percentages, variables
  • simple probability calculations
  • applications of other mathematical operations such as squares, square roots, etc
  • more advanced mathematical techniques and skills e.g. trigonometry
Estimate
  • estimating and rounding off (when requested) to whole number values or monetary units
  • estimating and rounding off to requested number of decimal places
  • making a contextual judgment re whether a found answer is realistic or not and changing the answer to the appropriate correct rounded (but not necessarily mathematically correct) answer.
Use formula/model
  • evaluating a given formula involving common operations (+, -, x, ÷)
  • developing/creating and using straight forward formulae
  • using strategies such as working backwards or backtracking (e.g. 15% of ? = $255)
  • generative reasoning
  • using and interpreting standard algebraic and graphical conventions and techniques
Measure
  • knowing common straight forward measures
  • naming, counting, comparing or sorting values or shapes
  • visualizing and describing shapes, objects or geometric patterns or relationships
  • making and interpreting standard measurements using common measuring instruments
  • using angle properties and symmetry to describe shapes or objects
  • estimating, making and interpreting measurements including interpolating values between gradations on scales
  • converting between standard measurement units within the same system
  • calculating measures of central tendency and spread for non-grouped data
  • converting between non-standard measurement units within the same system
  • counting permutations or combinations
  • converting between measurements across different systems
Interpret
  • locating/identifying data in texts, graphs and tables
  • orientating oneself to maps and directions such as right, left, etc
  • reading and interpreting data from texts, graphs and tables
  • following or giving straight forward directions
  • interpolating data on graphs
  • calculating distances from scales on maps
  • generating, organising, graphing non-grouped data
  • extrapolating data
  • reading and interpreting trends and patterns in data on graphs, including slope/gradient
  • graphing grouped data
  • calculating measures of central tendency and spread for grouped data
