The motivation for developing this work came from observing, in theory and in practice, that the introduction to algebraic thinking in elementary school is surrounded by countless failures, which often makes it traumatic. This book is the result of constant work to improve mathematics education. It is the fruit of reflections, seeking effective teaching solutions for successful learning in mathematics, especially algebra.
