Mamut Matemáticas Sumar 1 es un cuaderno autodidáctico, que se trata con el concepto de sumar, practicando las sumas con números pequeños de 0 a 10. El libro sirve mejor el primer grado. Es la version español del libro Math Mammoth Addition 1.

El libro comienza con problemas muy fáciles que usan ilustraciones y números de 0 a 5. Esto lo hace facil al niño para entender y efectuar las sumas.

Los problemas que faltan sumando siguen poco después, porque son muy importantes en el entendimiento de invertir el proceso de sumar (restar). Primero se utilizan ilustraciones, y poco a poco se alcanza los problemas abstractas 1 + __ = 5 con sólo símbolos y números.

El libro contiene muchos lecciones que se llaman Sumas con... que tienen la meta de ayudar al niño con la memorización de las tablas de suma del 1 a 10. Para esta meta, el libro contiene una leccion para cada suma: Sumas con el 5, sumas con el 6, etcetera. (Por favor vease las páginas de muestra.)

Por ejemplo, en la leccion Sumas con el 6, el niño practica las siguientes sumas de la tabla de sumar:
0 + 6
1 + 5
2 + 4
3 + 3

De esta manera, el libro provee mucha practica, y también una estructura lógica para aprender las tablas de sumar.

Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
