Critical Language
Language Usage
A student in 6th grade will demonstrate the ability to apply and comprehend critical language by interpreting the problem, choosing the appropriate operation, explaining a solution strategy, comparing the location of numbers on a number line, and describing the location of coordinates on a graph.
