Description

This Finding the Area in Square Centimeters Worksheet helps third grade students learn to measure the area of a figure by counting the unit squares that cover it. Area is the amount of flat space a shape takes up, and one of the clearest ways to introduce it is with a centimeter grid where every square stands for one square centimeter. As students count the shaded squares inside each figure, they build a strong, hands-on understanding of what area really means long before they memorize any formula.

This printable 3rd grade area worksheet gives students three kinds of practice on one clean, colorful page. First they count the squares inside three different figures — including a rectilinear shape — to find each area in square centimeters. Next they shade their own squares to build figures with a given area, and finally they solve a short word problem and explain their thinking in writing. Teachers can use it for independent practice, math centers, morning work, or homework, and the included answer key makes checking quick and simple.

What’s Included

  • 1 print-ready PDF worksheet
  • Answer key
  • Three count-the-squares figures, two build-a-figure grids, and a solve-and-explain word problem

There are three big reasons this Finding the Area in Square Centimeters Worksheet works so well. First, counting real squares connects the idea of area to something students can see and touch, so the concept truly sticks. Second, the build-a-figure section turns students from passive counters into active problem-solvers who create shapes of their own. Third, the write-and-explain question asks students to put their reasoning into words, which deepens understanding and prepares them for multiplying side lengths later on.

To extend the learning, hand students centimeter grid paper and challenge them to draw the largest and smallest figures they can that share the same area. Cover a book, a tile, or a lunch tray with square sticky notes and count them together to measure real objects. You can also play a partner game where one child names an area and the other shades a matching figure, then they trade papers and check each other’s work. These simple activities keep area practice playful while reinforcing the very same skill.
