DokunSay · Concrete + Digital
The system that makes number tangible: DokunSay
DokunSay is a family of materials for learning abstract number by touching, seeing and saying. Physical sets work in the classroom and at home; seven digital tools run in the browser in five languages.
Physical materials
Dotted Number Rods
Raised dots on each rod let the child feel the magnitude of a number; the core tool for subitising, comparison and number bonds.
Number Tablets
Digit, word and dot pattern on one surface (Triple-Code). Their effect on preschool arithmetic was studied in published research (Mutlu, 2018).
Arithmetic Tablets
Build addition and subtraction through part–whole relations; a bridge to place value.
Clock Teaching Material
Separates the hour and minute hands by colour and layer; clock-reading difficulty is an early sign of dyscalculia (Mutlu & Korkmaz, 2020).
Seven digital tools
One pedagogical language, one accessibility standard: large touch targets, font scaling, high contrast, read-aloud. Turkish, Kurmanji, English, Arabic and Persian (right-to-left supported). Open source under the MIT licence.

Concrete → Representational → Abstract
Every DokunSay tool presents a concept in three stages: a physical or digital manipulative, a visual representation (number line, diagram), then the symbol. Learners move between stages at their own pace.
