Solve problems involving addition and subtraction of fractions, including those with unrelated denominators (ACMNA153)

[/title][fusion_text]LO: To add or subtract fractions with unrelated denominators.

Know:

  • how to add/subtract numbers

Understand:

  • that the addition of fractions makes the fractions larger
  • that the subtraction of fractions makes the fractions smaller
  • that when adding/subtracting fractions, you have to keep the denominator the same. If they are different you have to make them the same prior to proceeding.

Do:

  • I can add and subtract fractions with different/unrelated denominators
