The cuisenaire strips

As a result of the developmental processes and the experiences that children have when interacting with their environment, they develop numerical, spatial and temporal notions that allow them to advance in the construction of more complex mathematical notions. from a very early age and according to the stimuli they receive, they can establish relationships of equivalence, equality and inequality (more, less or equal quantity); they realize that "adding makes more" and "taking away makes less", and distinguish between large and small objects. their judgments appear to be genuinely quantitative and they express them in different ways in situations of their daily lives.
