Math Mammoth Introduction to Fractions contains fraction-related material suitable for approximately grades 2-4. This material does not include division or multiplication of fractions, nor adding unlike fractions. The lessons are mostly simple, introductory lessons to various fraction topics.
The one exception to the "easiness" is the topic of finding fractional parts of a whole using division. These lessons are in the end of the book. I have included them here since I have included the topic in my Math Mammoth Grade 4 Complete Worktext (LightBlue Series), and they are accessible for children in 4th
grade who have practiced single-digit division and long division.
Other than that, the topics covered are on a simple level, constantly illustrated with pictures, and with
small denominators. The presentation avoids spelling out specific rules for manipulating fractions, but instead relies on the usage of pictures on a very concrete level.
The topics covered are
one-half and fourth parts
concept of a fraction
concept of a mixed number
adding and subtracting like fractions
adding and subtracting mixed numbers with like fractional parts
equivalent fractions with pictures
comparing fractions - special cases.
finding fractional part of a whole using division
The lessons proceed so that the first two are suitable for second grade, and the rest are suitable for third or for fourth grade.
The answers are in the back of the book.
