Montessoripedagogiskt syfte
Designat för att främja barnets självständighet och koncentration
Transform abstract fractions into an intuitive, tactile experience with this classical Montessori mathematical material, designed to make proportions and fractional arithmetic crystal clear.
Concrete Mathematical Visualisation
Following Maria Montessori's principle of moving "from the concrete to the abstract", children physically manipulate circular segments. They easily discover that two halves or four quarters form one whole (1/2 + 1/2 = 1; 2/4 = 1/2), establishing deep conceptual comprehension rather than rote memorisation.
Comparative Equivalence & Arithmetic
Children can overlay segments to test fraction equivalences, compare ratios, and solve early addition and subtraction equations with visual self-correction.
Precision Laser-Cut Hardwood
Manufactured from sustainably harvested birch plywood with laser-etched fractional values and smooth non-toxic colour staining.
