Math Mammoth British Money is a worktext that covers money-related topics usually encountered during years 2-4. The book contains both textbook explanations and exercises, and is designed to be very... More > easy to teach from, requiring very little teacher preparation. The book starts with year 2 topics, such as counting coins with pence-amounts and easy problems about change. From there, the lessons advance toward year 3, and finally to year 4 topics, such as practising with pound amounts, and figuring out total bills and change.< Less

Math Mammoth Percent teaches students the concept of percent, percentage of a number, discounts, sales tax, percent of change, circle graphs, and percent of comparison. It is suitable for 6th-8th... More > grade.
The concept of percent builds on a student's understanding of fractions and decimals. Specifically, students should already be very familiar with the idea of finding a fractional part of a whole.
One lesson concentrates a on tenth of a percent. Thus far, all the material has been with whole percents. From this lesson on, we will also use tenth of a percent (such as 13.4%). We compare ratios, fractions, and percent. Students study how to make a circle graph.
Last is percent of change dealing with decreases and increases in quantities (such as prices). We also study how to find the percent of change when the original and new amount are known.< Less

Math Mammoth Geometry 3 can be used after the student has finished Math Mammoth Geometry 1, and is suitable for grades 5-7. This book does not require the students to calculate area or volume, and... More > that is why it is not necessary to study Math Mammoth Geometry 2 (which deals with those topics in depth) before this book.
We start out with basic angle relationships, such as adjacent angles (angles along a line), vertical angles, and corresponding angles (the last only briefly). The lesson Angles in Polygons is a sequel to studying angles in a triangle.
The next set of lessons deals with congruent and similar figures.
The last section of this book teaches some basic compass-and-ruler constructions.
Note: At this time (2014), this book is in "beta" stage. It will be revised with more lessons (such as about The Pythagorean Theorem) probably in early 2015.< Less

The book starts with year-2 topics such as counting coins with cent-amounts and easy problems about change.
From there, the lessons advance toward year-2 and finally to year-3 topics, such as practising with dollar amounts, and figuring out total amounts owed and change.< Less

Math Mammoth Statistics & Probability is a worktext with instruction and exercises, meant for grades 5-7.
The book starts with the easiest topics, such as reading different graphs. Then we study... More > histograms and various kinds of line graphs, including how to draw them.
The book also deals with mean, median, and mode—the three measures of central tendency—how to use them, and how these concepts relate to line and bar graphs.
We also study, range, and stem-and-leaf plots and the concept of distribution, which is a fundamental theme in the study of statistics.< Less

Math Mammoth Integers worktext covers all important integer (signed numbers) topics for middle school (grades 5-8), with instructions written directly to the student.
The first topic in the book is... More > integers themselves, presented on a number line (negative and positive numbers) and tied in with temperature. Next we move on to modeling additions and subtractions as movements on a number line. Another model used in the book for addition is that of counters or chips. One lesson explains the shortcut for subtracting a negative integer using three different viewpoints (difference, counters, and number line movements).
Multiplication and division of integers is explained using counters, first of all, and then relying on the properties of multiplication and division. We use multiplication and division in the context of enlarging or shrinking geometric figures in the coordinate grid.< Less

Math Mammoth Decimals 2 is a book about decimal place value and the four operations with decimals. It is most suitable for 5th and 6th grade.
The book starts with a short review of previously learned... More > concepts (from Math Mammoth Decimals 1):
place value with tenths and hundredths, and adding and subtracting decimals that have tenths and hundredths.
The rest of the book is spent learning the four operations of decimals with numbers that have up to three decimal digits, and especially concentrating on decimal multiplication and division.< Less

Math Mammoth Subtraction 1 is a self-teaching workbook that deals with the subtraction concept within 0-10, initially as 'taking away', but soon presenting other situations where subtraction is... More > used:
* Finding how much MORE something is as compared to something else - the difference.
* Two (or more) parts making up a whole (of something). This is approached as a missing addend problem.
All these situations are taught explicitly and can be found in the word problems throughout the book.
Also, students learn to use the addition facts to find the answer to subtraction - in essence to memorize the basic subtraction facts, which are based on the addition facts.
While this book is not tied to any grade level, it is most suitable for first grade. Answers are appended.
This book ties closely in with Math Mammoth Addition 1.< Less

Math Mammoth Measuring 2 is a worktext that covers time, temperature, length, weight, and volume related lessons, aimed for 4th-5th grade. The focus in these lessons is on calculations that involve... More > conversions between different measuring units.< Less
