Addition Strategies 1. Strategy: When one of the numbers is 1, 2, or 3, start with the bigger number and count on. See: 7+2=___ Think: 7…8, 9 See 3+9=___ Think: 9…10, 11, 12     Counting on 1, 2, 3 2. Turnarounds Strategy: In addition, turnarounds have the same answer. See: 9+2 Think: 2+9=11, so 9+2= 11   3. Zero Facts Strategy: When 0 is added to any number, the number stays the same. See: 6+0=___ Think: 6 See: 0+9=___ Think: 9   4. Doubles Strategy: When the numbers are the same, think of the picture.
