Whole Curriculum Adaptation for Maths
Most learning apps adapt within a single topic – if your child struggles with a question, they see an easier one.
HeyKitsu goes further. Our Whole Curriculum Adaptation looks across everything your child is learning and builds a path that makes sense.
If they're confident with fractions but finding ratio problems challenging, we'll adjust – and we'll also recognise when strengthening decimals and percentages will unlock that ratio understanding.
The result is a learning journey that builds connections between topics, strengthens weaknesses and keeps your child challenged across the entire maths curriculum.
