03　Answers and one-line notes

#	Answer	One-line note
1	407	The tens digit is 0 but must still be written, so the number is 407.
2	860	Take away 100 to get 800, then add 60 back: 860.
3	683	The hundreds are equal, so compare the tens: 8 beats 3, so 683 is greater.
4	600	Two hundreds plus three hundreds make five hundreds, and the two fifties add one more hundred: 600.
5	427	Ones 12 − 5 = 7, tens 9 − 7 = 2, hundreds 7 − 3 = 4, giving 427.
6	693	Largest 942 minus smallest 249 gives 693.
7	825	Carry from the ones and the tens: 6 + 9 and 3 + 8 + 1, giving 825.
8	242	After borrowing twice the answer is 242.
9	360	180, 240, 300, 360: the third number is 360.
10	545	The tens digit 1 needs to borrow before subtracting 7, giving 545.

04　What to do after marking

After marking, redo only the wrong items and write down which step went wrong (formula, unit, or misread number).
Repeat the same item two days later; move to the next paper only when both attempts are correct.
Parents only need the answer and note columns; there is no need to explain every item.
