      Item Type(s):
      This benchmark will be assessed using: MC, GR items.
      At Grade 7, this benchmark will be assessed using MC and GR items.
      Clarification: Students will identify the next step needed to solve a linear equation.

      Students will use different strategies, including working backwards, to solve problems that can be represented as a one- or two-step linear equation.
      Content Limits: Items involving finding a solution should be limited to a single variable on one side of the equation.

      Items identifying formulating an equation for a situation may involve two variables.

      Items may not exceed two procedural steps and four operational steps.

      Items may not include irrational coefficients.
      Stimulus Attributes: Items should be set in a real-world or mathematical context.

      Items may include equations, graphs, tables, or real-world situations.
      Response Attributes: Negative grids will be used in this benchmark.
