Numbers 1-20 Recognition

Meet Numbers 1 to 20

Our Learning Goal

I can recognise and match numbers from 1 to 20.

What number words or numerals do you already know?

Use this to surface prior knowledge. Expect a mix of number names, numerals, and favourite numbers from 1 to 20.

What Is a Number?

• A number tells how many

• We use numbers every day

• We can say a number

• We can see a number written

Emphasise that a number name and a numeral both stand for the same amount.

Numbers 1 to 5

1 one

2 two

3 three

4 four

5 five

Count Small Groups

• Count each object once

• Touch or point as you count

• The last number tells how many

Model careful counting so pupils do not skip or count an object twice.

Numbers 6 to 10

6 six

7 seven

8 eight

9 nine

10 ten

Seeing 10 as a Group

• 10 is an important number

• We can make a full group of ten

• Ten helps us count bigger numbers

This prepares pupils for teen numbers by treating ten as one full group.

What does the last number you say tell you?

A

How many

B

What colour

C

How big

D

Where it is

Checks understanding from slides 2 to 6 that counting tells how many, and the last number said gives the total amount.

Counting and groups of ten

A number tells how many. When we count, we point to each object once. 10 is a full group of ten and helps us count bigger numbers.

All blanks come from the first teaching block: what numbers mean, careful counting, and seeing ten as a full group.

Numbers 11 to 15

11 eleven

12 twelve

13 thirteen

14 fourteen

15 fifteen

Teen Numbers

• Teen numbers are more than 10

• They are 10 and some more

• Example: 12 = 10 and 2 more

Keep examples concrete with counters or cubes if teaching live.

Numbers 16 to 20

16 sixteen

17 seventeen

18 eighteen

19 nineteen

20 twenty

Match Number to Amount

• A numeral matches a set of objects

• 7 matches seven things

• 14 matches fourteen things

• Count to check the match

Stress that matching means the written numeral and the counted set show the same amount.

Recognising Numbers Quickly

• Look at the shape of the numeral

• Say its name aloud

• Think of its amount

• Practise helps you know it fast

Which number means 10 and 2 more?

A

11

B

12

C

14

D

20

Targets the key teen-number idea from slides 7 to 8.

Teen numbers and matching

Teen numbers are more than 10. They are 10 and some more. The numeral 14 matches fourteen things when we count to check the match.

10

14

fourteen

20

40

twelve

sixteen

Reinforces teen numbers, numeral recognition, and matching a written number to an amount.

How can you recognise a number quickly?

Look for answers showing that students use numeral shape, say the number name, or think of the amount. Accept simple phrases such as 'say it', 'look carefully', or 'count it'.

What is one thing you learned today?

Reflection only. Invite simple responses about a number, counting, teen numbers, or matching numerals to amounts.

What helped you learn numbers best?

Reflection only. Students may mention counting objects, using groups of ten, saying number names, or matching numerals.
