About this resource

What's inside this resource

Systems of Equations UNIT TEST

The Systems of Equations UNIT TEST is a comprehensive tool designed to assess students' understanding of the 8th Grade Expressions & Equations Standards. It focuses on understanding and solving simultaneous linear equations, aligned with specific Common Core standards.

Assessment Focus :
  • Examining points of intersection on graphs
  • Solving two variable linear equations algebraically
  • Estimating solutions through graphing these equations
  • Discerning simple cases by inspection
  • Solving real-world problems leading to two linear equations in two variables.

Educational Aid

This education aid includes a 25-question test available in both hard copy format and Google Forms format. The question type breakdown consists of:

    Vocabulary tests, Testing solutions or simple cases by inspection tests;
    Understanding solutions on a graph (including estimating solutions);
    Substitution method;
    Elimination method;
    Word problems including one constructed response scenario.

Evaluation and Grading Ease

This test also incorporates Student Answer Sheets for easy marking, while also saving on printing costs. Also included is an answer key for quick corrections - saving teachers' time spent on grading papers!

Note:Fittingly designed for grade 8 Math curricula with emphasis towards Algebra sub-subjects-- this prime resource is conveniently delivered as PDF file types that work across devices seamlessly. It can be utilized for whole group instruction—to gauge overall class comprehension over systems-of-equation concepts—or smaller focus groups or even as homework tasks. Its utility versatility is only bound by individual teacher styles or student-centric goals!

Teaching tips & learning objectives

Learning objectives

  • Match systems-of-equations vocabulary terms, such as substitution method and elimination method, to their definitions.

  • Determine a system's solution from a graph or algebraically, including one-solution, no-solution, and infinite-solution cases.

  • Solve a system of two linear equations using the substitution or elimination method.

  • Set up and solve a system of equations to answer a real-world comparison problem, such as comparing two pay structures.

Teaching tips

  • Use the Google Forms link on page 1 if you prefer to administer the test digitally instead of the included PDF.

  • Print the two blank Student Answer Sheets back-to-back to save paper, as the file itself notes.

  • Review the constructed-response answer key's worked solutions before grading, since two valid approaches to the pay-comparison problem are shown.

Skills covered

  • Systems-of-equations vocabulary — students match terms like substitution method and elimination method to their definitions.

  • Graphical solution interpretation — students identify a system's solution, or recognize no-solution and infinite-solution cases, from a graph.

  • Algebraic solving methods — students apply substitution and elimination to solve systems of two linear equations.

  • Real-world modeling — students translate word problems, including a two-part pay-comparison scenario, into systems of equations and solve them.

Good to know

Questions teachers ask about this resource

What does the constructed-response question ask students to do?

Students set up a system of equations comparing two car-salesman pay plans, solve for the sales amount where both plans pay the same, then decide which plan pays more at $18,500 in weekly sales.

Is there a digital version of the test?

Yes — alongside the printable PDF, page 1 links to a Google Forms copy that can be saved to a teacher's Google Drive and shared through Google Classroom.
