Ccted found Sparx Maths:

• Moderately reduces teacher workload“AI being used to generate questions and extra questions if the child is motivated. Videos to help immediately with homework if needed.”
• Slightly reduces attainment gap“As a parent, I don't know the data. However it reviews facts with my son so that they are not forgotten between units of work.”
• Moderately improves teaching efficiency“If children are competing the homework, they will be more knowledgeable in the lessons. Data on the teacher's side would also help pinpoint where extra support is needed.”
• Significantly improves parent engagement“Weekend email to inform how much child has completed is useful as we are in a position to then encourage them to get on, rather than being told after the hand in date that it wasn't done.”
• Moderately improves attainment“My son is a good mathematician and highly engaged in the subject. However, he has realised there are some areas he is less sure about and Sparx has supported him to understand.”
