03　Answers and one-line notes

#	Answer	One-line note
1	3250 m	3 x 1000 + 250 = 3250 m.
2	6080 m	6.08 x 1000 = 6080 m; shift the decimal point three places.
3	750 g	0.75 x 1000 = 750 g.
4	3850 g	4.7 kg = 4700 g, and 4700 – 850 = 3850 g.
5	3250 mL	2.5 L = 2500 mL, and 2500 + 750 = 3250 mL.
6	1080 mm	1 m 8 cm = 108 cm = 1080 mm; two conversions are needed.
7	3040 kg	3 x 1000 + 40 = 3040 kg.
8	12.5 L	12500 / 1000 = 12.5 L.
9	0 cm	9 m 60 cm is exactly 9.6 m, so the difference is 0 cm.
10	5005 g	5 kg = 5000 g, then add 5 g to get 5005 g; 5 g is not 50 g.

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.
