Number > Fractions Addition & Subtraction

Australian Curriculum Version 9 Says:

Solve problems involving addition and subtraction of fractions with the same or related denominators, using different strategies.

What this means

Adding fractions like 1/5 + 3/5 , where the denominators are the same and 1/3 + 2/6 where the denominators are related. This does not involve using a formal algorithm to add fractions.

  • This can be applied to different situations such as measuring cups, fractions of a meter.
  • Diagrams such as number lines can be used to help solve the problems. These are then recorded in fraction symbols i.e. 1/2 + 1/4

Tip

  • To understand fraction walls and fraction bars students need prior experience folding paper strips.
