Three- and four-digit numbers worksheet: Answers and working
Part A: Working out and filling in
1. 4, 0, 2
Reading from the right, the first digit is the ones, the second the tens, the third the hundreds.
From the right: 2 in the ones, 0 in the tens, 4 in the hundreds.
2. 7040
The thousands digit is 7. There are no hundreds, so what digit holds that place?
7 in the thousands, nothing in the hundreds so a 0 holds it, 4 in the tens, 0 in the ones: 7040.
3. 7998
Count on from 7996 and watch the ones digit: stop at the first one that is even.
Count on from 7996: the first number ending in 0, 2, 4, 6 or 8 is 7998.
4. 400
Each step adds 100. What is 100 more than 300?
100 more each time: 300 + 100 = 400.
5. 75
Start at 0 and add 25 for each small step, counting along to the arrow.
Count 25 a step from 0: the arrow is 3 steps along, at 75.
6. 6
Adding 8 has to give an even number. Is 8 odd or even, so which kind must the number be?
To give an even sum with 8, a number must be odd if 8 is odd and even if 8 is even: from 16 to 26 there are 6 of them.
7. 6421, 1246
For the biggest number, put the biggest digit in the thousands; for the smallest, the smallest digit.
Biggest: biggest digit first, 6 in the thousands. Smallest: smallest first, 1 in the thousands.
8. In 3849, the 4 stands for 40
In 3849, the 4 is in the tens place, so it stands for 4 tens: 4 × 10 = 40
Part B: Choose, or true or false
9. True
Look only at the ones digit of 6585: is it 1, 3, 5, 7 or 9, or 0, 2, 4, 6 or 8?
Look only at the ones digit, 5: 1, 3, 5, 7 or 9 means odd.
10. False
No need to add: just look at the ones digits of 734 and 558. Is each odd or even?
Look at the ones digits only: odd plus even is odd; two odds or two evens make an even number. 734 + 558 = 1292.
11. A. 9132
The thousands digits are all 9, so compare from the hundreds: find the smallest, and the tens if they tie.
All have 9 thousands, so compare from the hundreds: the smallest hundreds is smallest; if they match, compare the tens.
12. A. 60
The big jar is like 3 small jars of about 20 each. How many times do you add 20?
The big jar is about 3 small jars of about 20: about 60.
Part C: Word problems
Marking: 2 for the working, 1 for the answer, 1 for the sentence.
13. 4800 sheets
A carton is a thousand and a pack a hundred. There are no tens or ones, so what goes there?

14. 836
The back of the sheet is simply the next page. Which page comes straight after 835?
The back is the next page: 1 more than 835, page 836, an even page.
15. 2 ways
The total must be even. Ka-yan shows 4. Does Ka-lok need the same kind of number as 4 (odd or even), or the other kind?
For an even total, Ka-lok's number must be odd if 4 is odd and even if it is even: 2 of 1 to 5 are.
16. 6957 steps
6957 and 6014 have the same thousands, so compare from the hundreds, then the tens and ones.
Both have 6 thousands, so compare from the hundreds: 6957 is bigger.
17. C. 400
