Grades 6-8 Mathematics Program Overview

Grade 6 
In Grade 6, instructional time should focus on four critical areas: 
       1.  Connecting ratio and rate to whole number multiplication and division and using concepts of ratio and rate to solve problems.
       2.  Completing understanding of division of fractions and extending the notion of number to the system of rational numbers, which includes negative numbers.
       3.  Writing, interpreting, and using expressions and equations.
       4.  Developing understanding of statistical thinking.
