Math Fluency Tips

Addition Tricks

  • Break numbers into tens and ones (e.g., 8+7 = 8+2+5 = 10+5 = 15)
  • Use doubles (e.g., 7+8 = 7+7+1 = 14+1 = 15)
  • Practice "making 10" with numbers

Subtraction Shortcuts

  • Count up from the smaller number to the larger number
  • Break it into smaller steps (e.g., 15-7 = 15-5-2 = 10-2 = 8)
  • Use addition to check your answers

Multiplication Tips

  • Know your times tables by heart
  • Use the distributive property (e.g., 7×8 = 7×5 + 7×3 = 35+21 = 56)
  • Multiply by 10 and then adjust (e.g., 9×7 = 10×7 - 7 = 70-7 = 63)

Division Strategies

  • Think of division as the inverse of multiplication
  • Break down the dividend into parts (e.g., 56÷8 = (40+16)÷8 = 5+2 = 7)
  • Practice fact families (e.g., 7×8=56, 56÷8=7)
