Math Mammoth Grade 6-B Worktext is the student worktext for the second half of grade 6, and part of the Math Mammoth Grade 6 complete curriculum. This is the Canadian version, which means the materials use only metric units, it is formatted to letter size, and large numbers are formatted with a space (such as 400 000). However, keep in mind that the "Grade 6" refers to the U.S. grade 6, and corresponds roughly to Canadian school system's year 7. The 6-B worktext covers prime factorization, GCF, and LCM, fractions, integers, coordinate grid, geometry (quadrilaterals, area of triangles & polygons, volume of rectangular prisms with fractional edge lengths, surface area), statistics (concept of a distribution, measures of center, measures of variation, boxplots, histograms). The worktext contains both the necessary instruction and the problems and exercises (the 'text' and the 'work'; thus a "worktext"), and is for the most part self-teaching. Please note this student worktext does not contain the answers.
