How should error review be done?

Find the exact step that went wrong, redo the item yourself, then write the cause beside it.

Why practise the zeros in the middle?

Dropping a zero in reading or writing is the commonest P3 slip; 7 050 is read seven thousand and fifty.

03　Answers and one-line notes

#	Answer	One-line note
1	8 tens, that is 80.	The 8 sits in the tens place, so it is worth 80, not 8 hundreds.
2	4 007	Both the hundreds and the tens places are zero, so two zeros follow the 4 before the 7.
3	3 046	There is no hundreds part, so the hundreds place is written as zero to give 3 046.
4	5 099, 5 909, 5 990.	All three have 5 thousands, so compare the hundreds first: 0 is the smallest, then compare the tens of the other two.
5	2 625	Borrow 1 thousand as 10 hundreds, then subtract place by place to reach 2 625.
6	The largest is 7 420 and the smallest is 2 047; the difference is 5 373.	For the largest arrange the digits downwards; the smallest cannot start with 0, so 2 leads and 0 comes second.
7	10 001	Adding 2 reaches 10 000 and one more gives 10 001, the first five-digit number.
8	3 008; after adding 992 it becomes 4 000.	3 008 plus 992 fills the hundreds and tens places exactly, carrying 1 into the thousands place.
9	1 490 dollars.	2 350 minus 1 480 is 870, and 870 plus 620 is 1 490.
10	The tens part is dropped; the correct reading is seven thousand and fifty.	The hundreds digit is zero so it is read as “and”, and the 5 is in the tens place, which makes it fifty, not five.

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.
