Grade 6 - Patterns and Relations
Standard 6.PR.4 - Practice evaluating variable expressions with whole numbers.
Included Skills: Algebra
Demonstrate and explain the meaning of preservation of equality, concretely and pictorially. • Achievement Indicators: - 6PR4.1 Model the preservation of equality for addition, using concrete materials (e.g., a balance, pictorial representations), and explain and record the process. - 6PR4.2 Model the preservation of equality for subtraction, using concrete materials (e.g., a balance, pictorial representations), and explain and record the process. - 6PR4.3 Model the preservation of equality for multiplication, using concrete materials (e.g., a balance, pictorial representations), and explain and record the process. - 6PR4.4 Model the preservation of equality for division, using concrete materials (e.g., a balance, pictorial representations), and explain and record the process. - 6PR4.5 Write equivalent forms of a given 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).
