ARI Curriculum Companion – Working with Two-Dimensional Measurement
In this section, the lessons focus on the concepts of area, perimeter, and volume. The eighth grade
lessons focus on understanding and applying the Pythagorean Theorem.
These lessons form an outline for your ARI classes, but you are expected to add other lessons as needed
to address the concepts and provide practice of the skills introduced in the ARI Curriculum Companion.
Some of the lessons cross grade levels, as indicated by the SOL numbers shown below. Such lessons
help students connect the content from grade to grade and to accelerate.
