Mamut Matemáticas Valor posicional 3 enseña los números de cuatro cifras, o sea números que tienen millares, centenas, decenas, y unidades.

Primero estudiamos valor posicional. El énfasis es en familiarizarse con números que tienen millares y 'visualizarlos' en una línea de números (vease una muestra).

Después se estudia suma y resta utilizando estos números.

El libro contiene muchos problemas mentales con números de 4 dígitos. Con estudiar suma y resta mental, se recalcan las semejanzas con suma de números menores, lo cual ayuda a los estudiantes a entender como sumar/restar estos números mayores (vease una muestra). Matemáticas mental también ayuda con el desarollo del sentido de números.

Suma y resta en columnas es una lección completa en sí misma. Estos procesos deberían ser relativamente fáciles ahora si el estudiante ya los ha dominado bien, al estudiar números de 2 y 3 dígitos.

Se estudia el orden de las operaciones para suma y resta (vease una muestra), y se hacen varias conexiones interesantes con pensamiento algebraico en esta lección.

Hay varias lecciones sobre redondeo y estimación (vease una muestra), los cuales son destrezas muy importantes que se necesitan en la vida diaria.

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.
