Operaciones Simples (II). Sumas y Restas. Comparación y Equivalencia. Recursos de Ajedrez. En esta 2ª parte de los Volumenes que dedicamos a las Operaciones Simples os presentamos 6 ejemplos de ejercicios diferentes con los que podrán practicar nuestros alumnos este tema. Presentamos en primer lugar unos ejercicios donde sustituimos las cifras por piezas de ajedrez, a las que podemos dar el valor standard o cambiar por otros valores que nos interesen. A continuación un par de ejercicios de comparaciones y equivalencias, utilizando nuevamente las piezas de ajedrez, sustituyendo a las cifras standard. En los Cuadrados casi magicos, utilizamos tableros de ajedrez de distintos tamaños para la práctica de Sumas, reforzando ademas los conceptos ajedrecísticos de filas, columnas y Diagonales. Los problemas de recorrido de piezas sobre el tablero se prestan a multitud de ejercicios, tanto de este tema, sumas, como otros que iremos viendo en distintos volumenes de nuestra Biblioteca de Recursos. De una forma divertida practicamos los movimientos de las piezas y las sumas correspondientes. En el último ejemplo de cálculo de valor de las piezas, estas no se corresponden con su valor standard y el alumno debe encontrarlo, mediante los cálculos correspondientes.

Señala con un círculo el símbolo correcto:

n+p= > < r+l n+p= = n+p

r+L= > < L+l l+p= = n+p

P+p= > < N+n N+n = = q+p

L+l= > < N+n L+l = = r+p

q+R= > < R+r n+P= = L+l

q+p= > < R+r R+r= = Q+p

n+r= > < l+N n+q= = R+r+n

Q+N= > < n+R l+N= = n+p+p

n+l= > < q+p n+q = = R+r+n

q+p= > < l+N+R q+p= = n+N+N

r+L= > < N+R+N q+R= = R+r+L

q+R= > < Q+q+P l+N= = n+P+p

L+p= > < R+p+n r+L= = n+n+p

l+N= > < R+r+p P+p= = p+p+p


CUADRADOS CASI MÁGICOS. Traza una raya sobre la línea (columna, fila o diagonal), que sume lo marcado.


RECORRIDOS SUMANDO: ¿Qué recorrido debe realizar la Pieza de Ajedrez para conseguir la suma indicada? Es obligatorio sumar en cada movimiento una cifra. El Caballo puede saltar por encima de una cifra sin sumarla. Las demás piezas no.


¿Qué peón coseguirá, moviendo y capturando, la suma indicada? Señala el camino


CÁLCULO. Calcula el valor de las piezas para que sumen lo indicado en las filas, columnas y diagonales.
