Numbers Count

Strong for Primary maths
Not evaluated for Secondary maths

Intervention description

Numbers Count is a maths intervention targeted at primary school pupils who may struggle to reach Level 3 by the end of KS2. It may be delivered on a one-to-one basis or with a small group of up to three children. There are two versions of the intervention: one for children in Years 1-3, and one for children in Year 4-6 and beyond (the intervention can be used with KS3 pupils).

Numbers Count creates an 'in-house specialist' mathematics teacher who helps raise standards for all learners. A specially trained teacher gives learners at least three 30-minute lessons a week for a term, individually or in twos or threes. After a detailed diagnostic assessment, the teacher plans a tailored programme for each child. Lessons focus on number and calculation. The teacher liaises with parents and shares their specialist knowledge with colleagues informally and through structured CPD, raising standards for all learners.

Staffing requirements

The intervention is delivered by a specially trained teacher in the form of at least 40 lessons over a period of 3 or 4 months, which supplement normal maths lessons.

Professional development/training

The Every Child Counts partnership runs the intervention, and offers intensive training and support to Numbers Count teachers over their first 2 terms through a local ECC Teacher Leader.
