He will also announce everyone has to study maths until they are 18 to boost numeracy levels.
The PM is to make a major speech outlining his blueprint for a “better future” — with a focus on easing the backlog of cases in the NHS likely.
The cost of living crisis will also be a focal point, as well as getting a grip on the small boats issue in the Channel.
He will also say giving every child the highest possible standard of education was “the single most important reason why I came into politics”.
He will say: “This is personal for me. Every opportunity I’ve had in life began with the education I was so fortunate to receive.
“With the right plan – the right commitment to excellence – I see no reason why we cannot rival the best education systems in the world”.
He will start bringing about the changes in this Parliament and complete the work afterwards.
Eight million adults in this country have the numeracy skills of primary school children and only half of 16-19 year olds study any maths at all.
The majority of major nations including Australia, the US, France and Canada all teach some maths up until 18 allowing them to deal with personal finances or mortgages confidently.
He will add: “One of the biggest changes in mindset we need in education today is to reimagine our approach to numeracy.”
It comes ahead of a keynote speech by Labour leader Sir Keir Starmer tomorrow.
