Teachers at Criftins C of E Primary School, in Dudleston Heath, near Ellesmere, say that the Maths-Whizz program has been a vital tool to children's education. The program uses artificial intelligence (AI) to mirror the behaviour of a human tutor through interactive learning and numbers games, in order to tailor maths lessons to each child's individual ability. Mandy Jones, headteacher at Criftins school, said: "Our pupils have enjoyed using Maths-Whizz throughout the closure period. "It meets the need of every child because there is enough scope and excitement to challenge the most able, as well as those who need support at every level. "We have been using it for several years but since the lockdown it has become all the more invaluable. It is widely accepted that the Covid-19 pandemic, which has resulted in many pupils being out of school since March, will produce substantial losses in learning that will be further impacted by the summer holidays. Experts say maths knowledge normally regresses by two to three months over the summer break due to lack of practice. This loss of learning is known as the'summer slide'. It means many schools will potentially face disruption in September – with pupils struggling to catch up. Richard Marett, CEO of global learning company Whizz Education, which supplied Maths-Whizz, said: "Many parents are rightly concerned about their child's education.
