ORELA Middle Grades Math: Perimeter & Area Chapter Objectives

The state of Oregon has now switched from the ORELA Middle Grades Math examination to a National Evaluation Series test for this subject area. The examination is used to assess the skills of those wishing to teach basic math to middle school students.

The Middle Grades Math exam is a computer-based test that includes 150 multiple-choice questions. The questions come from four main content areas: number sense and operations; algebra and functions; measurement and geometry; and statistics, probability and discrete mathematics. Perimeter and area are covered within the measurement and geometry content area, which makes up 25% of the test questions. Specifically, the questions may ask you to calculate or estimate the perimeter or area of a shape. You are allotted four hours and fifteen minutes to complete the exam, and you must earn a score of 225 or higher to pass.
