• • take precise measurements using specialized equipment (e.g.) a tape measure, a scale
  • make indirect measurements using geometry and trigonometry
  • measure curved or irregular surfaces
  • measure an angle
  • calculate amounts required (e.g.) the number of tiles required for a floor
  • calculate areas, perimeters, volumes
  • calculate total load weights
  • calculate a percentage
  • calculate a trajectory
  • calculate ratio, average, rate, proportion
  • use scientific notation, powers, roots
  • use formulae, equations, algebraic problems
• data analysis math (analysis of numerical data)
  • analysis of statistics
  • determining what is higher, lower or bigger, smaller
  • compare a numerical read-out to a range of numbers considered acceptable
  • compare rates, averages, etc.
  • calculate average rates of return on investments
  • compare monthly sales volumes
  • make projections
  • calculate impacts of different variables on pay and benefits packages
• numerical estimation (tasks that involve any estimation that results in a number)
  • estimate amount of material to be used
  • estimate time a task will take
  • estimate costs
  • estimate load weights
  • estimate numbers of workers required
  • estimate time available
  • estimate amounts that can be produced from raw materials
  • estimate number that will be sold

Some considerations:

• the need to use specific math foundations (math skills, concepts or knowledge areas):
  • number concepts: whole numbers, integers, fractions, decimals, percentages, powers/roots, scientific notation, significant digits. (Workers read, write, count, round-off, add, subtract, multiply and divide numbers.)
  • number patterns and relations: formulae, equations, rates, ratios, proportion
  • shape and special sense: areas, perimeters and volumes, measurement conversions, geometry and trigonometry (using sine, cosine, tangent, cotangent, secant and cosecant ratios to solve the unknown side of an angle or triangle)
  • statistics and probability: calculating averages, analysing data, using mathematical theories of probability
