Georgia Department of EducationGeorgia Standards of Excellence Grade 6 MathematicsCurriculum Map RationaleUnit 1: Extending students’ experience with whole number computation in elementary grades, division of fractions by fractions and all four operations ondecimals are a focus in the first unit. Tasks utilize hands-on activities as a means to building understanding, rather than rote memorization of algorithms.Students also find common factors and multiples and deepen and extend their understanding of the distributive property to work with fractions.Unit 2: Students work extensively with ratios and rational thinking through tasks and activities that generate deep understanding. The unit explores unit rateand comparative “size”, while focusing on real-world problems.Unit 3: Students begin a more formal study of algebra as they move from arithmetic experiences to algebraic representations. Students learn to translate verbalphrases and numeric situations into algebraic expressions, understand like-terms, and work with exponential notation.Unit 4: Extending the study of algebra, students reason about and solve one-step equations and inequalities. Often two quantities are not balanced or equal,and this unit introduces them to inequalities and how numbers compare, including work with number lines.Unit 5: Students extend their work with area and volume from simple figures in elementary school to more complex figures, including those with sides offractional lengths. Complex figures will be composed and decomposed into familiar triangles and rectangles in order to compute their areas. Nets of solidfigures allow students to calculate the surface area of three-dimensional figures.Unit 6: Students are introduced to the study of statistics, first by learning what constitutes a statistical question, then by collecting data through such questionsand data sorting and analyzing. Statistical measures allow for the description of data through single-number summaries of center and distribution, and studentsexplore and become familiar with what data “looks like” and find meaning in their samples.Unit 7: Up to this point, students have only encountered numbers with values greater than or equal to zero (Natural Numbers, Counting Numbers, and WholeNumbers). Unit 7 introduces students conceptually to circumstances best described with negative numbers, numbers with a value less than zero- the set ofIntegers. Integer operations are taught in seventh grade, but by introducing students to integers in sixth grade, they have the opportunity to explore situationsappropriately represented by negative numbers, and graph points in all four quadrants of the coordinate plane. Using a number line, students learn aboutnumbers and their “opposites” (additive inverses), and absolute value (distance from zero). This unit is intentionally placed at the end of sixth grade, as it is notan expectation of the standards for sixth grade students to do any operations with integers. Instead, this unit is intended as an introduction. It leads directly intothe first seventh grade unit, Operations with Rational Numbers.Richard Woods, State School SuperintendentJuly 2016 Page 3 of 7All Rights Reserved
