6th Grade Math (North Dakota Content Standards)

Mathematical Attributes, grades 6–8 (MA)

• 6-8.MA.P Analyze information, make a flexible plan for real problems, check the solution makes sense and revise (applies to grades 6–8).
• 6-8.MA.C Make connections within and across concepts, with examples and evidence (applies to grades 6–8).
• 6-8.MA.R Reason logically, using evidence to evaluate and explain thinking (applies to grades 6–8).

Number and Operations (NO)

• 6.NO.NS.1 Show how nonzero rational numbers relate to their opposites on number lines and what zero means in context.

Algebraic Reasoning (AR)

• 6.AR.RP.1 Describe ratio relationships with ratio language and models, part-to-part and part-to-whole.
• 6.AR.RP.2 Describe and calculate unit rates using rate language and models.
• 6.AR.RP.3 Use ratio tables, tape diagrams, double number lines and equations to solve ratio and rate problems.
