Critical Language
Language Usage
A student in 6th grade will demonstrate the ability to apply and comprehend critical language by describing how two-dimensional shapes can be used to represent three-dimensional figures, interpreting a problem to determine which measures are involved, explaining how formulas are related to the shape itself, and explaining a solution strategy.
