INTRODUCCION.

El presente trabajo constituye un conjunto de actividades numéricas para la suma llevada hasta el 100. Estas actividades se corresponden con cada una fases en que podemos descomponer el proceso de la suma llevada y constituyen la expresión, en forma de lenguaje matemático, del movimiento que realiza el pensamiento del alumno cuando lleva a cabo acciones prácticas que implican una suma llevada. La numeración de las distintas actividades, se corresponde con las distintas fases. Lo anterior supone que estos cuadernos son la culminación de una serie de actividades prácticas que los alumnos han tenido que realizar con diversos recursos materiales didácticos, especialmente con regletas. Es por ello que si se pretendiesen aplicar sin realizar dichos ejercicios prácticos, perdería gran parte de su efectividad.
