Mastery tools

Representations are used in lessons to expose the mathematical structure being taught. They are not new – we can probably all remember using counters when we were children. The history of mathematics uncovers many examples of objects, pictures or symbols used in early maths to represent concepts. Nowadays it’s not unusual to find tens frames, Dienes blocks, Cuisenaire® rods, bar models and other representations in frequent use in (...) classrooms.
