Victorian Essential Learning Standards (VELS) MATHEMATICS
Number Level 4
At Level 4, students comprehend the size and order of small numbers (to thousandths) and
large numbers (to millions). They model integers (positive and negative whole numbers and
zero), common fractions and decimals. They place integers, decimals and common fractions on
a number line. They create sets of number multiples to find the lowest common multiple of the
numbers. They interpret numbers and their factors in terms of the area and dimensions of
rectangular arrays (for example, the factors of 12 can be found by making rectangles of
dimensions 1 × 12, 2 × 6, and 3 × 4).
Students identify square, prime and composite numbers. They create factor sets (for example,
using factor trees) and identify the highest common factor of two or more numbers. They
recognise and calculate simple powers of whole numbers (for example, 24 = 16).
Students use decimals, ratios and percentages to find equivalent representations of common
fractions (for example, 3/4 = 9/12 = 0.75 = 75% = 3 : 4 = 6 : 8). They explain and use mental
and written algorithms for the addition, subtraction, multiplication and division of natural
numbers (positive whole numbers). They add, subtract, and multiply fractions and decimals (to
two decimal places) and apply these operations in practical contexts, including the use of
money. They use estimates for computations and apply criteria to determine if estimates are
reasonable or not.
