Step 1

NumberNames

Step 1 – Number Names

 - Being introduced to numbers  - Naming numbers  - Using multi sensory approaches  Support:  - Parroting  - Exposed to number songs  - Books with numbers  - Pointing to numbers around the environment

Step 2 – Number Sequences

 Numbers are in a fixed unbreakable

• rder

Support:

 - Counting objects to them  - Counting while doing activities (i.e. items

• f clothing while getting dressed, steps

when walking up the stairs)

Step 3 – 1:1 Correspondence

Associating numerals to a value  1:1 touch correspondence  Understanding that anything can be counted  Support:  - counting a small group of objects using 1:1 touch correspondence after positioning them in a line  - counting objects in pictures  - Discussing now many days are in the week, seasons…

Step 4 –Cardinal values

 The last number said represents a quantity  The quantity remains the same no matter where you start

 Support

 - Continue counting objects and pictures  - Repeat sentence stems ‘The last number I said was 5, I have counted 5 dots, so altogether there are 5 dots’

Step 5 -Subsidising

 Estimating  Identifying a number without counting

 Support:  - Identifying dice patterns  - Knowing how many fingers are being held up on a set

• f hands

 - Estimation games (covering a small group of objects, revealing them for a few seconds and then covering them again)

Step 6 -Visualising

 Numbers stand for different things  Visualising the value/ quantity represented by a numeral  Support:  - Discuss numbers in different contexts: I am 10 years old, I take the number 10 bus to go home, I have 10 pencils in my pencil case.  - Look out for numerals or quantities in the environment: I can see 4 birds over there, you have number 4 on your top, that car has 4 wheels

Step 7 -Comparing

 Expanding their mathematical vocabulary  Forwards, backwards  Fewer, more, greater than, less than  Understand that numerals represent a value that can be compared  Support:  - Using everyday language (there are two forks – would that be enough for you, mummy and your sister?, you just ate a banana, there are fewer bananas in the bowl now)

Top Tips

 Take your time  Do not skip steps  Repeat to consolidate
