Grade 7 - Patterns and Relations
Standard 7.PR.3 - Use proportional relationships to solve a word problem.
Included Skills: Ratios
Demonstrate an understanding of one-and two-step linear equations of the form ax/b + c = d (where a, b, c, and d are whole numbers, c less than or equal to d and b does not equal 0) by modeling the solution of the equations concretely, pictorially, physically, and symbolically and explaining the solution in terms of the preservation of equality. • Model the preservation of equality for each of the four operations using concrete materials or using pictorial representations, explain the process orally and record it symbolically. • Generalize strategies for carrying out operations that involve the use of the preservation of equality. • Solve an equation by applying the preservation of equality. • Identify and provide an example of a constant term, a numerical coefficient, and a variable in an expression and an equation. • Represent a problem with a linear equation and solve the equation using concrete models, (e.g., counters, integer tiles) and record the process symbolically. • Draw a representation of the steps used to solve a linear equation. • Verify the solution to a linear equation using concrete materials or diagrams. • Explain what the solution for a linear equation means. • Represent a problem situation using a linear equation. • Solve a problem using a linear equation.
