Since being trained in [email protected] 1 and 2, I have seen both of our Teaching Assistants in action and the children have responded so well. The training has been a huge benefit to them and the school team.

1st[email protected]:

  • provides targeted use of the Pupil Premium
  • supports the National Curriculum for Mathematics
  • raises mathematical attainment
  • increases enjoyment and engagement in mathematics
  • develops teaching assistants’ subject knowledge and wider effectiveness
  • provides detailed evidence of progress and impact.

Three programmes are available to schools:

Becoming 1st[email protected] – for children who need further support to secure the Early Learning Goal for Number.

1st[email protected] 1 – for children who need further support at the level of the Year 1 curriculum. UPDATED 2022

1st[email protected] 2 – for children who need further support at the level of the Year 2 curriculum.

How Does it Work?

1st[email protected] 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 1st[email protected] 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 1st[email protected]

An independent EEF trial found that 1st[email protected] 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 1st[email protected]
  • An optional school visit by the Trainer.

1st[email protected] 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.
