This content descriptor sets out learning for Year 7 Mathematics. Use it to plan lessons and assessment with the Australian Curriculum v9.
Elaborations
- • Elaboration investigating equivalence of fractions using common multiples and a fraction wall, diagrams or a number line to show that a fraction such as 2/3 is equivalent to 4/6 and 6/9 and therefore 2/3<5/6
- • Elaboration expressing a fraction in simplest form using common divisors
- • Elaboration applying and explaining the equivalence between fraction, decimal and percentage representations of rational numbers; for example, 16\%, 0.16, 16/100 and 4/25, using manipulatives, number lines or diagrams
- • Elaboration representing positive and negative fractions and mixed numerals on various intervals of the real number line, including intervals that are not symmetrical about zero
