What is the number system?
The number system refers to subitising, counting and ordering, recognising numerals, and understanding place value.
Identification – what you may see in the child or young person
Subitising
- Needs to count a small number of objects or dots to work out ‘how many’ (they can’t subitise).
- Unable to identify the number of objects in a collection by partitioning it into smaller quantities (for example, if given 7 objects, they can’t ‘see’ that this is 4 and 3 and use this to know there is 7 altogether).
Counting and ordering
- Finds it difficult to count a collection of objects or pictures accurately
- Finds it particularly difficult to count backwards.
- Makes mistakes when counting aloud – for example 70, 80, 90, 20.
- Finds it hard to ‘count on’ – for example, to solve 6 + 3, they say ‘1,2,3,4,5,6…7,8,9.’
- Finds it difficult to remember what number each numeral represents.
- Muddles ‘teen’ and ‘ty’ numbers (for example 13 and 30).
- Has difficulty ordering numbers.
Place value
- Misreads or miswrites numbers – for example, they record 61 for 16.
- Doesn’t understand the value of digits in two or three-digit numbers.
- Doesn’t understand the value of 0 as a place holder
Older pupils
- Finds it hard to link place value to multiplying and dividing by 10, 100, 1000 etc
Planned provision in school
Based on need, some of this provision will be effective.
- Provide extra opportunities to practise subitising – for example, play games with dice and dominoes that help the child or young person know ‘how many’ without having to count.
- Help the learner to build their own base ten representations such as straws or lolly sticks bundled into 10s.
- Provide sentence starters and stem sentences to support the use of full sentences.
- Pre-teach the language used to access maths lessons – for example, before, after, greater than, less than.
- Provide 1:1 precision teaching (focused on the child or young person’s identified area of need – for example, recall of digits, or fluent recognition of small quantities).
- Plan pre-teaching based on the Connective Model of maths to support understanding.
- Provide 1:1 or small group support. For example –
- use the ‘Supporting children with gaps in their mathematical understanding‘ materials. These were aimed at children and young people in Key Stage 2.
- use ‘Spot on with number,’ 1:1 or small group (up to four children). This is for Key Stage 1 children with moderate difficulties in maths, or older children and young people with specific difficulties, including dyscalculia.
- use ‘From Counting to Calculating,’ a small group intervention to support children who lie just above the bottom 5% in Year 2 and for children older than this who are working significantly behind age related expectations. Contact the Devon maths team.
- for older pupils, plan support based on the NCETM’s mastery materials.
