IDL Numeracy is a maths software resource that helps to improve ability for low-attaining learners in mathematics. It includes a fully graded course to support the National Curriculum for KS1 (Key Stage 1) maths and KS2 (Key Stage 2) maths. In order to be inclusive, the lessons in IDL are designed to reduce the stress those with dyscalculia would ordinarily feel when faced with mathematical problems. After a few hours using IDL, learners will find a familiarity with the lessons and because the lesson mechanics remain the same, they gain the confidence they need to tackle problems, even those they have never encountered before.
