Numbers to 20 worksheet: Answers and working
Part A: Working out and filling in
1. 15
Touch each one as you count it and never count one twice. If there are lots, ring 10 first.
Touch each one as you count: the last number is 15, so there are 15.
2. 5, 4, 9
Recognise each dice at a glance, then count on from the bigger one.
Know the patterns: 5 and 4, which make 9.
3. 6
Counting back takes 1 away each time. What is 1 less than 7?
Counting back, each is 1 less: after 7 comes 6.
4. 19
Counting on adds 1 each time. What comes straight after 18?
Counting on, each is 1 more: after 18 comes 19.
5. 2
Start with the first on the left and say “first, second…” until you reach 🚗.
Count from the 1st on the left: 🚗 is 2nd.
6. 9
First work out how many stand behind Ka-lok. From the back, Ka-lok comes straight after them.
13 − 5 = 8 stand behind Ka-lok, so from the back Ka-lok comes next: 9th.
7. 12
Count on from 11 and watch the ones digit: stop at the first number whose ones digit is even.
Count on from 11: the first number ending in 0, 2, 4, 6 or 8 is 12.
8. 4
Count on from 4 up to 8 and keep track of how many steps that takes.
Counting on from 4 to 8 takes 4 steps, so the other part is 4.
9. 1 + 19 = 20
1 goes with 9 to make ten, and one more ten: 9 + 10 = 19, 1 + 19 = 20
Part B: Choose, or true or false
10. True
Count how many there are in the picture first, then compare that with 1.
There are 9. The later a number comes when you count, the bigger it is: compare 9 with 1.
11. B
Picture how a dice shows 2: how are the dots laid out? No need to count each one.
Know the dice patterns: the one showing 2 can be seen at a glance, with no counting.
12. A. 13
Look at the ones digit of each number: an odd number ends in 1, 3, 5, 7 or 9.
13 ends in an odd digit: in twos, 1 is left over, so 13 is odd.
Part C: Word problems
Marking: 2 for the working, 1 for the answer, 1 for the sentence.
13. 19 hair clips
A full box of 10 is 1 ten. Count on from 10 for the extra ones.
A box is 1 ten; with 9 ones that makes 19.
14. 9 steps
Recognise each dice at a glance first, then count on from the bigger one.
Seen at a glance: 4 and 5, so 9 steps.
15. 10
The next number is the one that comes straight after 9 when you count on.
The next number counts on: 1 more than 9 is 10.
16. 18
Even numbers come every other number, 2 apart. What is 2 more than 16?
Even numbers come every other number: the next after 16 is 18.
17. 9 cars
The 15 cars split into red and white. Count on from 6 to 15 and keep track of the steps.
15 splits into 6 red and 9 white.
18. A box holds 20 cookies. Tsz-ching's family ate some, and 12 are left in the box. How many cookies did they eat? (Answer: 8 cookies)
