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

  Elaborations

  • using different ways to add and subtract fractional amounts by subdividing different models of measurement attributes; for example, adding half an hour and three-quarters of an hour using a clock face, adding a $\frac{3}{4}$ cup of flour and a $\frac{1}{4}$ cup of flour, subtracting $\frac{3}{4}$ of a metre from 2 $\frac{1}{4}$ metres
  • representing and solving addition and subtraction problems involving fractions by using jumps on a number line, or bar models, or making diagrams of fractions as parts of shapes
  • using materials, diagrams, number lines or arrays to show and explain that fraction number sentences can be rewritten in equivalent forms without changing the quantity, for example, $\frac{1}{2}+\frac{1}{4}$ is the same as $\frac{2}{4}+\frac{1}{4}\mathrm{ }$
