Formulas: Area/Perimeter [TEKS Tools Grade 5]

This post specifically looks at how formulas can be used solve problems involving area and perimeter. Read more about TEKS Tools and their rationale here.

Formulas

Formulas, the fourth TEKS Tool, account for around 7% of each 5th grade STAAR test. These formulas are applied to solve problems related to area, perimeter, and volume.

The main function of a formula is to understand the relationship between quantities. In fourth grade, students were first introduced to the formulas for area and perimeter of squares and rectangles. In fifth grade, they are introduced to the formula for volume of a rectangular prism.
