El cuaderno Mamut Matemáticas Dinero es un cuaderno sobre el dinero estadounidense (US). Abarca temas que usualmente se estudian en los grados 1-3. El libro contiene los explicaciones y ejercicios, y es diseñado ser muy fácil utilizar en la enseñanza. El libro requiere muy poca preparación por parte del profesor. (Solo hay que hallar algunas monedas de antemano para la práctica).

El libro comienza con temas del primer grado, como contar pennies, nickels, dimes, y quarters. Aunque las lecciones utilizan dibujos para representar las monedas, practicar con monedas reales es aún mejor, por supuesto.

Después de esto, las lecciones avanzan hacía los temas del segundo grado, y al fin hasta los del tercer grado. Por eso, el estudiante puede completar las lecciones de este libro durante varios periódos de tiempo, dependiente del nivel actual del estudiante. No es necesario estudiar todas en uno solo periódo.

Dar vuelto explica dos maneras básicas de hallar el vuelto: contar ascendentemente, y restar (hallar la diferencia). Todo esto se hace con matemáticas mental. La siguiente lección también practica problemas con dinero utilizando matemáticas mental.

En la última lección resolvemos problemas con dinero sumando y restando cantidades de dinero verticalmente (en columnas).

La clave está al final del libro.

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.
