Using visual representations to help pupils understand how to convert fractions into fractions with a common denominator may help. For example, using pizza or pie slices (3/4 of a pizza is the same as eating 15/20 of a pizza because you are slicing each 1/4 into 5 pieces.) The class could play 'The price is right' whereby children guess whether the next fraction to be pulled out of a bag is going to be higher or lower than the previous one. If they are correct, they have another go! Children may be challenged to convert fractions into fractions with a common denominator to prove they are correct.
