Addition-5th

Grade-level Expectations for 5th Grade - Recognize equivalent representations for the same number and generate them by decomposing and composing numbers - Apply and describe the strategy used to compute up to 5-digit addition or subtraction problems

Example Strategy: 1,483 + 3,358 = 1,000 + 3,000 = 4,000 400 + 300 = 700 80 + 50 = 130 3 + 8 = 11 4,000 + 700 + 130 + 11 = 4,841

Example Strategy: 5,997 + 2,768 = (5,997 + 3) + (2,768 - 3) = 6,000 + 2,765 = 8,765
