|
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)

conventions and techniques
|
Measure | | | | |

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

and patterns in data on graphs,
including slope/gradient
|
- graphing grouped data
- calculating measures of
central tendency and spread
for grouped data
