Subtraction at Grade 3 uses the same number range as addition. Expectation B2.5 asks students to subtract whole numbers within totals of 1000. The printable preview opens with 325 − 222, which needs no trade, then 146 − 127 and 352 − 159, which do. 202 − 104 forces a trade across a zero in the tens place. A later item hides the starting number in __ − 41 = 93, and a short story takes 76 marbles away from 79. That mix is what families usually want from a Grade 3 subtraction worksheet: the algorithm, the zero, and one situation to read.
