Notes for Fractions Powerpoint

August 3, 2009

Some ideas I had from reading The Life of Fred: Fractions:

  • The notes should include several circles that students can practice dividing into fourths, sixths, etc.
  • Also use the notes so that they can color in shapes to see equivalent fractions.
  • Practice filling in “ruler” fractions (1/8, 1/4, 3/8, etc.)
  • Dividing three pizzas between eight people
  • Use commutative property to show how to cancel when multiplying.
  • Use “opposites” to show why dividing by a fraction is the same as flipping and multiplying.
  • Include dimensional analysis as part of multiplying fractions.
