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.
Greatest Common Factor (GCF)
Least Common Multiple (LCM)
The factors and multiples of numbers are used to classify and compare numbers.
Integers allow values to be described relative to a fixed point.
Situations dictate a need for different operations.
