  3. Demonstrate fluency with addition and subtraction facts with sums or differences to 10 by decomposing a number leading to a ten.
    Example: 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9
  4. Demonstrate fluency with addition and subtraction facts with sums or differences to 10 by using the relationship between addition and subtraction.
    Example: Knowing that 8 + 4 = 12, one knows 12 - 8 = 4.

  • Decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9)
  • Using the relationship between addition and subtraction
    (e.g., knowing that 8 + 4 = 12, one knows 12 – 8 = 4)
  • Creating equivalent but easier or known sums
    (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13)
Note: Computational fluency is demonstrating the method of student choice. Students should understand the strategy he/she selected and be able to explain how it can efficiently produce accurate answers.
