Math Mammoth Grade 6-B worktext (Canadian version)
is the second student book for sixth grade, and part of the Math Mammoth Grade 6 complete curriculum.
This book contains chapters 6-10 of the curriculum.
In chapter 6, we first review
prime factorization
, and then study the greatest common factor and the least common multiple.
Chapter 7 first presents a thorough review of
fraction operations
from 5th grade (addition, subtraction, and multiplication). The topic of focus in the chapter is fraction division. Students also do some problem solving with fractions.
In chapter 8, students are introduced to integers. They plot points in all four quadrants of the coordinate plane and learn to add and subtract with negative numbers. Multiplication and division of integers are studied in 7th grade.
In geometry (chapter 9), the focus is on
the area of polygons
. This is studied in a logical progression: first, the area of right triangles, then the area of parallelograms, then, the area of triangles, and lastly the area of polygons. We also review some topics from earlier grades (quadrilaterals, perimeter, basic drawing). Other major topics in this chapter are calculating
surface area
of some solids using nets, and volume of rectangular prisms with fractional edge lengths.
Lastly, in chapter 10, students study
statistics
. The focus idea is that of a statistical distribution. Students learn about measures of center and measures of variability, and how to summarize distributions using those. They learn how to make dot plots, histograms, boxplots, and stem-and-leaf plots.
This curriculum is essentially the same as the U.S. version of Math Mammoth, only customized for the Canadian audience in these aspects:
The curriculum uses the metric measurement units. Since Canadians do use imperial units, such as inches and pounds, in some contexts, the curriculum does mention them, but not often.
The spelling conforms mostly to American English, taking into account a few key differences where Canadian English follows British English.
Numbers are formatted with a space as a thousands separator, and a point as a decimal separator.
Page (paper) size is Letter.
The US version of the curriculum is aligned to the Common Core Standards, which means this curriculum may not be properly aligned to the sixth grade standards in any Canadian province. However, you can probably find material for any missing topics in the neighbouring grade levels of Math Mammoth materials.
Available separately, Math Mammoth Grade 6-A worktext covers the first half of 6th grade math. Also available are the answer keys and a book containing cumulative reviews and chapter tests.
