Use area models to represent the distributive property and develop understandings of addition and multiplication (all positive rational numbers should be included in the models)(MGSE3.MD.7)
Generate equivalent expressions using properties of operations and understand various representations within context. For example, distinguish multiplicative comparison from additive comparison. Students should be able to explain the difference between 3 more and 3 times(MGSE4.0A.2; MGSE6.EE.3, MGSE7.EE.1,2;MGSE9-12.A.SSE.3)
Evaluate formulas at specific values for variables. For example, use formulas such as A = l x w and find the area given the values for the length and width(MGSE6.EE.2)
Use square root and cube root symbols to represent solutions to equations of the form x2 = p and x 3 = p, where p is a positive rational number(MGSE8.EE.2)
