Number Skills 0-10
This item has no instructions
Our learning goal
I can say, read, write, count, order and compare numbers from 0 to 10.
This item has no instructions
What number words or numerals from 0 to 10 do you know?
Use this as a quick warm-up. Invite pupils to share any numerals, number words or ideas such as zero, count, bigger or smaller.
State numbers 0-10 in order
The numbers in order are:
0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
Emphasise that the order stays the same every time. Pupils may want to start at 1; remind them that this lesson includes 0.
What comes next?
Each number is 1 more than the number before it.
0 → 1 → 2 → 3 → 4 → 5 → 6 → 7 → 8 → 9 → 10
Use finger counting or a class number line to show the pattern of adding one each time.
What comes before?
Each number is 1 less than the number after it.
10 → 9 → 8 → 7 → 6 → 5 → 4 → 3 → 2 → 1 → 0
Children often find counting backwards harder than forwards. Keep the rhythm steady and point to each numeral if possible.
Zero is a number too
0 means none
It comes before 1
It belongs in the number order
This slide helps prevent the common idea that counting must always begin at 1.
Which number comes before 1?
2
0
3
10
Checks the key misconception from this section: 0 belongs in the counting order and comes before 1.
Counting order
The numbers from 0 to 10 stay in the same order. Each number is 1 more than the number before it. When we count backwards, each number is 1 less than the number after it. The number 0 means none, but it is still a number.
Echoes slides on forward order, backward order and the meaning of zero.
Count items up to 10
When we count objects, we say one number for each item.
The last number we say tells us how many there are.
Model one-to-one correspondence clearly by touching or moving each object once only.
Count carefully
Start at one item
Touch or point to each item once
Say the numbers in order
Stop when every item has been counted
Watch for double-counting and skipped objects, especially when items are not in a straight line.
The last number tells how many
If we count 1, 2, 3, 4, 5, there are 5 items.
The final number names the total.
This is the key idea of cardinality. Keep examples small and visible.
Count sets in any arrangement
Items can be in a line, a group or a scattered set.
If we count each item once, the total stays the same.
Useful misconception check: children may think a longer line has more even when the number of objects is unchanged.
When counting objects, what does the last number tell us?
Where to start
How many items
Which item moved
How to line up
Tests cardinality: the final number named gives the total quantity.
Counting objects
When we count a set, we say one number for each item. We should touch or point to each item once only. When every item has been counted, the last number tells us how many there are, even if the items are in a scattered set.
Reinforces one-to-one correspondence, counting once only, and that arrangement does not change the total.
Count on up to 10
Counting on means starting from a number we know and saying the next numbers.
Example: start at 4 and count on: 5, 6, 7
Stress that counting on does not always start at 0 or 1.
Start from a number
Start at 2: 3, 4, 5
Start at 6: 7, 8, 9
Start at 8: 9, 10
Invite pupils to notice that the starting number is not repeated when they count on, unless you are explicitly naming the start first.
One more
Counting on by one finds one more.
7 → 8
8 is one more than 7.
Connect this to comparing numbers later: larger numbers are further on in the counting sequence.
Count on to find a new total
If there are 5 items and 2 more are added, we can count on:
6, 7
Keep this concrete rather than formal addition. The purpose is the counting-on strategy.
If you start at 6 and count on, which number do you say first?
5
6
7
8
Checks that pupils do not repeat the starting number when counting on.
Counting on
Counting on means starting from a number we know and saying the next numbers. If we start at 8, we say 9 and 10. Counting on by one helps us find one more.
Uses the examples and language directly from the counting-on slides.
Write numbers 0-10
We can write these numerals:
0 1 2 3 4 5 6 7 8 9 10
Use correct numeral formation vocabulary if needed, but keep the slide focused on recognising the written forms.
Numerals match number words
A numeral is the written symbol for a number.
For example, the number word five matches the numeral 5.
This distinction supports later reading and writing tasks.
Ten is written with two digits
Numbers 0 to 9 use one digit
10 uses two digits: 1 and 0
It still names one number: ten
Pupils may read 10 as separate digits. Reinforce that it is the number ten.
Read numbers 0-10
When we see a numeral, we say its number name.
Example: 3 is read as three.
Point from symbol to spoken word. Keep the link direct and repetitive.
Read these number names
0 zero
1 one
2 two
3 three
4 four
5 five
Pause briefly on zero because it is less familiar in early counting routines.
Read these number names
6 six
7 seven
8 eight
9 nine
10 ten
If needed, draw attention to common visual confusions such as 6 and 9.
Which numeral matches the number word ten?
1
0
10
9
Targets the important idea that 10 is one number written with two digits.
Reading and writing numerals
A numeral is the written symbol for a number. The number word five matches the numeral 5. Numbers 0 to 9 use one digit, but 10 uses two digits.
Checks the link between number words and numerals, plus the special case of 10.
Arrange numbers in order of value
To arrange numbers, put them from smallest to largest or from largest to smallest.
Use the language of value consistently: a number's value tells how much it represents.
Smallest to largest
Numbers in increasing order:
0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
Link increasing order to moving forwards on a number line.
Largest to smallest
Numbers in decreasing order:
10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0
Link decreasing order to moving backwards on a number line.
Use a number line to order
Numbers further right are greater.
Numbers further left are smaller.
This prepares for comparison: position on the number line shows value.
Compare numbers
We can compare numbers to tell which is greater, smaller or equal.
Use consistent vocabulary rather than many synonyms.
Greater than and less than
8 is greater than 5
3 is less than 6
A number further on in the count is greater
Tie comparison back to order, not just memorised statements.
Equal numbers
Two numbers are equal when they have the same value.
Example: 4 and 4 are equal.
You may also show equal sets of objects to connect numeral comparison with quantity.
Compare sets and numerals
We can compare:
the number of objects in two sets
two written numerals
a set and a numeral
Useful bridge slide: the same number ideas apply to objects, spoken numbers and written numerals.
On a number line, which number is greater?
The one on the left
The one in the middle
The one on the right
They are always equal
Connects ordering to position on the number line.
Order and compare
To arrange numbers, we can put them from smallest to largest or from largest to smallest. A number further right on the number line is greater. Two numbers with the same value are equal.
Brings together the final section on ordering and comparing values.
What is one thing you learned about numbers 0 to 10?
Expected ideas: something specific such as zero comes before one, the last number tells how many, count on starts from a known number, 10 has two digits, numbers can be ordered from smallest to largest, or greater/less/equal language.
What helped you understand today’s lesson best?
Invite metacognitive reflection. Useful answers may mention number lines, counting objects, saying numbers aloud, matching words to numerals, or comparing sets.
Which part felt hardest today?
Encourage honest reflection about challenge points such as counting backwards, remembering zero, reading 10, or comparing greater and less.
