Math Mammoth Multiplication Division 3
Elementary Math Workbook

Math Mammoth Multiplication Division 3 workbook is a self- explanatory worktext, dealing with multiplication and division with 3-and 4-digit numbers, divisibility, factoring, and primes.

The book is not tied to any grade level; you can use it in various situations where the child needs to understand or practice these topics. However, it most closely matches 4th - 5th grade math.

(The number 3 on the title just refers to the fact I have also written Multiplication 1, Division 1, and Multiplication Division 2 books - so this one is the third one in the multiplication / division series.)

First are studied multiplying whole hundreds. Then, multiplying two-digit numbers and multiplying three-digit numbers in columns is explained. The book shows in detail how this algorithm is based on distributive property.

Several different estimating strategies are also explained.

Long division withing 0-10,000 is mainly for review; however learning about two-digit divisors requires some practice.

Divisibility rules, factoring and prime numbers are presented as new topics, with proper detail and depth of explanations and examples.

Please note that besides the problem sheets in this book, you can generate an unending supply of 3-digit multiplication and long division practice worksheets (for free) at Basic Operations Worksheets Generator.
