Exercise P Do you remember?
Non-calculatorMethod. Count on one at a time from 3.
- Start at 3. We count on from the number we have.3
- Say the next three numbers. Each number is one more than the one before.4, 5, 6
- Write the answer. 4, 5, 6
Check. Count back from 6 to 3: 6, 5, 4, 3. It matches.
Watch out. Start with the number after 3, not 3 itself.
Method. The bigger number is the one that comes later when we count.
- Say both numbers in order. Count 4, 5, 6, 7.4, 5, 6, 7
- Find the bigger one. 7 comes after 4 when we count.7 is later than 4

Touch each thing once as you say its number.
The last number you say tells you how many there are.

Exam tip
Grown-up tip. Lay out real things at home, such as buttons, pasta shapes or toy cars. Ask your child to move each one as they count it, then ask: “How many altogether?” Aim for accurate counting first, then speed. Ten counts in about ten seconds.

Seeing 1, 2 and 3 at once
You can often see a small group at once. You do not need to count one by one.
Look at the dots. Say the number. Then touch each dot once to check.
Key ideas
- Small groups can be seen at once.
- Check by touching each dot once.
- Practise until you can say 1, 2 and 3 quickly.
Method. Look at the dots, then check.
- Look at the whole picture. Two dots are easy to see at once.2 dots
- Touch each dot once. This makes sure none is missed.1, 2
- Write the answer. 2
Check. Counting gives 2 as well.
Watch out. Touch each dot once so you do not miss one.
Method. Look at the dots, then check.
- Look at the whole picture. There is only one dot.1 dot
- Touch the dot once. It is the only one.1
- Write the answer. 1
Check. One dot, so the answer is 1.

Watch out
Watch out. Dots can be spread out. Do not skip one because it is far away from the others.
Exam tip
Grown-up tip. Draw 1, 2 or 3 dots on paper, in any pattern. Ask your child to say the number straight away, then touch each dot to check.
