found Maths-Whizz by Whizz Education :

• Provides school data“Teachers find it very useful to be able to see a maths age for each strand of maths to identify exactly where support and challenge is needed and at what level.”
• Reduces attainment gap“We invite target pupils to a Maths Whizz club to ensure they achieve a minimum of 3 progressions a week and this has a positive impact on their attainment with the attainment gap narrowing for the majority of pupils.”
• Reduces teacher workload“Because the tutor automatically moves the children on in their learning, teachers report a reduction in their workload.”
• Improves teaching efficiency
• Improves parent engagement“Parents report positively of having a clearer understanding of where their children are in their maths learning.”
