Measurement Unit Conversions Workbook


Book Description

The workbook Measurement Unit Conversions contains lessons and exercises suitable for grades 5-7. First, we study how the basic concept of decimal numbers can help us convert measuring units. For example, since 0.01 means one-hundredth, then 0.01 m means one-hundredth of a meter -- which is the definition of a centimeter. Then we round and estimate quantities given in various measurement units, and find the error of estimation. After that, we focus on the metric system and conversions between the metric units of measurement. I have tried to emphasize sensible and intuitive methods for converting measuring units within the metric system, instead of relying on mechanical formulas. Next, we practice conversions between units in the customary system, using the basic conversion factors and multiplication and division. Then from there we advance to conversions between customary and metric measuring units. Later, students learn how rates can be used to convert measurement units. This method is inaddition to the methods for converting measurement units that were explained earlier in the workbook. It does not mean that students should "change over" and forget what they learned earlier - it is simply a different method for doing the conversions. Some students may choose one method over another; some may be able to master all of the methods. Most will probably choose one method they prefer for doing these conversions. Next, the lesson on maps gives a different real-world context for measurement units and conversions between them, since calculating the real distances from map distances or vice versa involves both using a scale ratio and conversion of the measurement unit used. Lastly, the lesson Significant Digits deals with the concept of the accuracy of a measurement and how it limits the accuracy of the solution. Significant digits is not a standard topic for middle school, yet the concept in it is quite important, especially in science. You can consider this topic as optional or reserve it for advanced students.




Prealgebra 2e


Book Description

The images in this book are in color. For a less-expensive grayscale paperback version, see ISBN 9781680923254. Prealgebra 2e is designed to meet scope and sequence requirements for a one-semester prealgebra course. The text introduces the fundamental concepts of algebra while addressing the needs of students with diverse backgrounds and learning styles. Each topic builds upon previously developed material to demonstrate the cohesiveness and structure of mathematics. Students who are taking basic mathematics and prealgebra classes in college present a unique set of challenges. Many students in these classes have been unsuccessful in their prior math classes. They may think they know some math, but their core knowledge is full of holes. Furthermore, these students need to learn much more than the course content. They need to learn study skills, time management, and how to deal with math anxiety. Some students lack basic reading and arithmetic skills. The organization of Prealgebra makes it easy to adapt the book to suit a variety of course syllabi.




Metric Units and Conversion Charts


Book Description

Metric Units and Conversion Charts A Metrication Handbook for Engineers, Technologists, and Scientists Second Edition Why waste your valuable time hunting for conversion factors, symbols, and units? With this handbook, you can convert from one measurement system to any other by means of 62 conversion charts covering almost every field of science. The charts are based on values published by the foremost authoritative sources such as the American National Standards Institute (ANSI), the International Organization for Standardization (ISO), and the Institute of Electrical and Electronics Engineers, Inc. (IEEE). The charts are universal, and so conversions can be made quickly and confidently. This much-expanded second edition has the following features: * The charts make a clear distinction between SI and other metric units by identifying SI units by red boxes. * Official symbols of all SI units are given, along with the name of the unit. * The recommended symbols for quantities are shown at the top of each chart. * A new chapter on mass, force and gravity explains how the units of force were established. * For introductory courses, chapters are included explaining quantity equations and numerical equations, together with worked-out examples. * For classroom work, over 100 review questions, together with answers.

Fundamentals of Mathematics


Book Description

Fundamentals of Mathematics is a work text that covers the traditional study in a modern prealgebra course, as well as the topics of estimation, elementary analytic geometry, and introductory algebra. It is intended for students who: have had previous courses in prealgebra wish to meet the prerequisites of higher level courses such as elementary algebra need to review fundamental mathematical concenpts and techniques This text will help the student devlop the insight and intuition necessary to master arithmetic techniques and manipulative skills. It was written with the following main objectives: to provide the student with an understandable and usable source of information to provide the student with the maximum oppurtinity to see that arithmetic concepts and techniques are logically based to instill in the student the understanding and intuitive skills necessary to know how and when to use particular arithmetic concepts in subsequent material cources and nonclassroom situations to give the students the ability to correctly interpret arithmetically obtained results We have tried to meet these objects by presenting material dynamically much the way an instructure might present the material visually in a classroom. (See the development of the concept of addition and subtraction of fractions in section 5.3 for examples) Intuition and understanding are some of the keys to creative thinking, we belive that the material presented in this text will help students realize that mathematics is a creative subject.
