03　Answers and one-line notes

#	Answer	One-line note
1	350 cm	1 m = 100 cm, so 3.5 x 100 = 350 cm.
2	2000 m	1 km = 1000 m, so 2 x 1000 = 2000 m.
3	4.5 km	1000 m = 1 km, so 4500 / 1000 = 4.5 km.
4	2400 g	1 kg = 1000 g, so 2.4 x 1000 = 2400 g.
5	3 L	1000 mL = 1 L, so 3000 / 1000 = 3 L.
6	50 mm	1 cm = 10 mm, so 5 x 10 = 50 mm.
7	1200 mL	1 L = 1000 mL, so 1.2 x 1000 = 1200 mL.
8	7000 kg	1 tonne = 1000 kg, so 7 x 1000 = 7000 kg.
9	8.5 kg	1000 g = 1 kg, so 8500 / 1000 = 8.5 kg.
10	600 cm	Going from metres to centimetres multiplies by 100, not 10: 6 x 100 = 600 cm.

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.
