Math Mammoth Metric Measuring


Math Mammoth Metric Measuring covers measuring related topics over the span of four grades (grades 1-4). The lessons for this book have been compiled from two of my books about measuring, and are presented here as a single book that only deals with metric units.

The PDF version of this book is enabled for annotation. This means that if you prefer, your student can fill it in on the computer, using the typewriter and drawing tools in Adobe Reader version 9 or greater.

The lessons cover measuring length, weight, and volume, measuring temperature in the Celsius scale, the 24-hour clock and elapsed time, and using decimals within the metric system in general. While the book contains something for all grades from grades 1 to 4, the bulk of the lessons are targeted for second and third grade.

This book contains both explanations of the material and exercises, and is thus termed a worktext. It is designed to be very easy to teach from, requiring fairly little teacher preparation; however in several lessons the teacher needs to gather measuring equipment beforehand, such as a ruler, a scale, or measuring cups.

This book is not organized by grade-levels nor with increasing difficulty. Instead, the lessons are grouped by topic. The first lessons in each section typically have hands-on exercises where the student uses suitable measuring equipment, and the last lessons in each section include problems about conversion between the units.

The very first lessons cover measuring length using centimeters and millimeters. Then we study meters and kilometers.

Children use the bathroom scales to weigh objects in kilograms. Other lessons teach grams and estimating weight. The goal is to let students become familiar with kilograms, and have an idea of how many kilograms some common things weigh.

The lessons include many hands-on activities so that the student gets first-hand experience in measuring, and has a basic knowledge of how "big" the units milliliter and liter are. One lesson also includes deciliters.

Metric System
In these lessons, students learn how to use decimal numbers within the metric system and the various prefixes.

The lessons deal with Celsius degrees, how to read a thermometer, changing temperature, and temperature line graphs.

The emphasis is in conversion between various time units, the 24-hour clock, and calculating elapsed time. The lessons do not cover how to read a clock; I have a separate book called Math Mammoth Clock that can be used to teach telling time.

When it comes to measuring, experience is the best teacher. We all use various measuring units in our everyday life, and using them is the key to remembering what they are and how to convert from one unit to another. The units your child is not using are likely to be forgotten easily. So encourage the young elementary students to have free “play time” with measuring devices such as scales, measuring cups, measuring tapes, rulers, and thermometers.

Excellent product. Have only done the metric length section so far and my daughter really enjoyed it. The explanations were clear and she could do a lot of the work independently. [...]

Thorough and complete, this worktext progressed through metric measuring in a logical manner. Covering distance, weight, volume, and temperature, this book taught my 3rd grader everything she needed to know up to and beyond her grade level. As the auth [...]

Original electronic
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.
