Adding Fractions with Different Denominators

To add and subtract fractions with different denominators students are taught to use equivalent fractions to find a common denominator.  As learning progresses numerical methods are used to find the lowest common multiple of the two fractions.  Completing fraction pyramids give the class an opportunity to consolidate and apply their learning.
Differentiated Learning Objectives
  • All students should be able to add and subtract fractions where one denominator is a factor or multiple of another using a fraction wall.
  • Most students should be able to add and subtract fractions where one denominator is a factor or multiple of another using equivalences.
  • Some students should be able to add and subtract fractions where neither number is a factor or multiple of the other.
