Extend understanding of preservation of equality concretely, pictorially, physically, and symbolically. • Model, and explain orally, the preservation of equality for addition, subtraction, multiplication, and division concretely (e.g., balances), pictorially, or physically. • Create, and record symbolically, equivalent forms of an equation by applying the preservation of equality (of a single operation) and verify the results concretely or pictorially (e.g., 3b = 12 is the same as 3b + 5 = 12 + 5 or 2r = 7 is the same as 3(2r) = 3(7)).
