What This Standard Means
What Students Need to Do
- Students measure the area of a plane figure by counting equal unit squares that cover it. They report the count with square units such as square centimeters, square inches, or improvised square units.
What Mastery Looks Like
- A student counts 24 square-centimeter tiles covering a figure and records an area of 24 square centimeters. The student organizes the count by rows to avoid missing or double-counting tiles.
Common Misconceptions
- Students may count grid lines, vertices, or only the outside tiles instead of square spaces. They may give a bare number or use centimeters instead of square centimeters.
How to Assess It
- Give students a gridded figure containing 21 unit squares. Ask for its area, unit label, and a counting method that can be checked.

Ways to Teach It
Cover irregular paper figures with unit-square tiles and count systematically by rows or labeled groups.
Ask students why an area answer needs square units rather than the linear unit used for side length.
Play area count challenge with gridded figures, including distractors that invite counting lines instead of squares.
Count square tiles needed to cover a small tray liner or section of a classroom display.
