This is the best programme we have ever had for teaching assistants. It was not only effective but children gained an enthusiasm for their maths work.

How Does it Work?

1stClass@Number comes ready-made with detailed session guidance and extensive resources. A specially trained teaching assistant delivers up to 30 half-hour sessions to a group of up to four children, for 10 -15 weeks. The children continue to take part in their normal class mathematics lessons.

The lessons focus on number and calculation, developing children’s mathematical understanding, communication and reasoning skills.  Stimulating, enjoyable games and activities engage the children and build their confidence. Each topic starts with a simple assessment that helps the teaching assistant to tailor sessions to the children’s needs.

The teaching assistant starts working with their group of pupils straight after the first training day. Then the training runs alongside the implementation of the teaching programme, so that the Teaching Assistant is trained topic by topic.

Impact on Achievement

Over 55,000 pupils in Years 1 to 11 have been supported by 1stClass@Number in 4,000 schools.

  • They made an average Number Age gain of 13 months in only 4 months – over 3 times the expected progress.
  • 93% of them showed more confidence and interest in learning mathematics in class after 1stClass@Number.

An independent EEF trial found that 1stClass@Number had a positive impact on mathematical skills, particularly for the lowest attaining pupils

Training and Professional Development

  • Delivered locally by an accredited ECC Trainer
  • 6 half days for teaching assistants – mathematical subject knowledge and pedagogy- adapting session plans to meet children’s needs
  • 2 half days for a school Link Teacher, with the TA, – supporting, managing & evaluating 1stClass@Number
  • An optional school visit by the Trainer.

1stClass@Number has made a remarkable difference, not only for our pupils but also for our TAs.  The high-quality training helped our TAs to become much more confident with mathematics – not just in delivering the intervention but also in supporting class mathematics teaching.
