The "Proportions" game, from Educa's "Learn and Have Fun" collection, is an educational game that teaches the relationship between numbers and proportions through manipulable mathematical rulers, a visual and tactile way to understand concepts of measurement and magnitude. The different pieces and activities included in the box allow children to compare sizes, order sequences, and associate numbers with quantities, promoting logical-mathematical reasoning progressively and without the pressure of a traditional school exercise. It is suitable for children from 5 years old, both for playing alone and with family, serving as a simple introduction to pre-algebra notions before entering more formal schooling, in a format that prioritizes experimentation over memorization. It is part of Educa's "Learn and Have Fun" educational collection, designed to accompany different learning stages throughout preschool.
