ECOF Maths KS2 - Success@Arithmetic 


A programme developed by the team at Edgehill University that developed the ‘Every Child Counts’ programme.


Success@Arithmetic is a calculation-based intervention for learners, primarily in Years 5 and 6,  who have difficulties with arithmetic proficiency and need support to improve their understanding of number and written calculation skills. 


Aim:  to raise attainment in mathematics for children with moderate difficulties 


How does the programme work: The class teacher conducts a diagnostic assessment and selects a series of Success@Arithmetic steps to form a tailored programme of up to 24 sessions, adapted from detailed plans that the LSA delivers to an intervention group of up to three pupils. The teacher supports the LSA in adapting the sessions to meet the specific needs of the children. 


3 x 40 minute sessions per week in addition to normal maths lessons

Programme lasts approximately 8 weeks


The sessions use number rods, bar modelling and written methods to build a complete mathematical picture, developing pupils’ arithmetic fluency.  It helps them to make faster progress and to catch up with their peers through a mastery approach.


Selection criteria:  It is designed for children in Year 5 and 6 who are attaining NC level 3c/3b+ needing to move towards level 4. 


Measuring impact: Entry and exit assessments (Sandwell Early Numeracy Test KS2-KS3) are completed to give a standardised Number Age score. 


Parents/carers must be informed if their child has been selected to take part in the programme
