  • Objective To explore multiplication using
    doubling and halving skills
  • Materials Required Paper and pencils
  • Steps
  • To solve 28 34
  • One student draws column A and other student
    draws column B. We can call column A half and
    column B doubles.
  • Each student then writes the factors as shown.
    The number in column A is halved and the one in
    column B is doubled repeatedly. When you have to
    half an odd number, ignore the remainder. Both
    students stop when 1 is reached in column A.
    Cancel all the even numbers from column A and its
    pair in column B.
