03　Answers and one-line notes

#	Answer	One-line note
1	April has only 30 days.	April, June, September and November each have 30 days; only February is shorter, and the other months have 31.
2	February has 28 days in a common year and 29 in a leap year.	February 2027 has only 28 days; 2028 is a leap year, so February 2028 has 29 days.
3	21 days.	One week has 7 days, so 3 weeks is 3 times 7, which is 21 days.
4	1 August.	July ends on the 31st, so the next day starts a new month: 1 August.
5	3 June.	Counting 11 days reaches 31 May, and 3 days remain, so the date is 3 June.
6	52 weeks and 1 day.	365 divided by 7 gives 52 remainder 1, so a year is 52 weeks plus 1 day.
7	Tuesday.	From the 10th to the 31st is 21 days, and 21 is a multiple of 7, so the weekday stays the same.
8	10 January 2028.	Eleven days finish December, then 10 more days fall in the new year, giving 10 January 2028.
9	182 days and 184 days.	The first half is 31 + 29 + 31 + 30 + 31 + 30 = 182 days, and 366 minus that leaves 184 days.
10	September has only 30 days, so change it to 1 October.	September has 30 days and no 31st, so the day after 30 September is 1 October.

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.
