Jessica Dymond found maths-whizz:

• Moderately builds student knowledge“Setting topics for consolidations tasks for homework”
• Moderately improves attainment“The regular users sometimes show improved attainment”
• Does not significantly reduce attainment gap“Often the children who need to close the gap do not access / have access at home”
• Does not significantly reduce teacher workload“If time around our current curriculum, activities are easy to plan”
• Does not provide school data
