These free worksheets help first grade students master the commutative property of addition through fill-in-the-blank exercises. Each worksheet contains 14 problems where students complete addition equations to demonstrate that changing the order of addends doesn't change the sum, such as showing 5 + 3 = 3 + 5.
These worksheets demonstrate the commutative property of addition — the principle that changing the order of addends does not change the sum. Students fill in missing values to show that two addition equations with swapped addends produce the same result. Aligned with first grade standards.
