Adding and Subtracting Fractions Game
  • Choose a game piece and have fun!!!
  • Use a scratch paper to determine the common denominators and add or subtract the fractions.
  • How to calculate: to find a common denominator, list out the multiples of each denominator. For example, for the equation 2/3 + 1/6, the multiples of 3 are 3,6,9,12,15,18, etc. The multiples of 6 are 6, 12, 18,etc. The least common multiple is 6. For the fraction 1/6, the denominator is already 6, so leave it. For the fraction 2/3, multiply the denominator by 2 to make it 6, and multiply the numerator by 2 also. This simply is multiplying by 1 or 2/2. Therefore, the equation changes to 4/6 + 1/6. Now, add theĀ  numerators, but keep the denominators the same. The answer would then be 5/6.
