Standard 6.PR.4 - Practice evaluating variable expressions with whole numbers.

Included Skills:

Demonstrate and explain the meaning of preservation of equality, concretely, pictorially, and symbolically.
• Model the preservation of equality for addition using concrete materials, such as a balance or using pictorial representations, and orally explain the process.
• Model the preservation of equality for subtraction using concrete materials, such as a balance or using pictorial representations, and orally explain the process.
• Model the preservation of equality for multiplication using concrete materials, such as a balance or using pictorial representations, and orally explain the process.
• Model the preservation of equality for division using concrete materials, such as a balance or using pictorial representations, and orally explain the process.
• Write equivalent forms of an equation by applying the preservation of equality, and verify using concrete materials [e.g., 3b = 12 is the same as 3b + 5 = 12 + 5 or 2r = 7 is the same as 3(2r) = 3(7)].
