Math Mammoth Add & Subtract 3 workbook
Math Mammoth Add & Subtract 3 deals with various adding and subtracting topics, this
time with three-digit numbers. The book is good to study right after the student has learned place
value till 1000.
This book best fits second or third grade math; however it is not in tied to any grade level and does not mention anything about being for a specific grade level.
The goal in Math Mammoth Add & Subtract 3 is to add and subtract both mentally and in columns within 0-1000.
First the book explores mental math topics. We study adding and subtracting whole hundreds (see sample),
whole tens (See sample), and ones within 0-1000, often comparing to similar problems within 0-100. Also covered is rounding to nearest ten and how to estimate sums and differences using rounding.
In most lessons the addition or subtraction is first illustrated with pictures so the student can learn the concepts. You can obviously also use manipulatives to this end.
The latter part deals with adding and subtracting in columns within the range 0-1000,
explaining in detail the how you carry to both tens and hundreds (adding), or how you borrow
two times (in subtracting).
Typically the processes of carrying (See sample) or borrowing (See sample) are first
practiced using picture exercises, to ensure the student also understands what is going on.
The lesson Another Way to Subtract explains a different subtraction algorithm which may be easier for some children.
Besides problems practicing these processes, many of the lessons also have word problems (See sample),
puzzles, problems with money, and other types of exercises.
