This area of rectangles worksheets resource contains everything you need to teach, practice, and review finding area:
Area of Rectangles Mini-Lesson:
Kick off your area unit with a no-prep interactive notebook lesson! Students learn the three main methods for finding area:
Counting unit squares
Multiplying length × width
Tiling with equal-sized rectangles
This reference page keeps learning visual and straightforward — with simple cut-and-glue setup and no folding required.
10 Area Worksheets:
Students explore area through a variety of practice pages, including:
Counting squares to find area
Using multiplication to find area of rectangles
Finding area through tiling
Comparing which rectangle has the greater area
Shaded vs. unshaded area
Finding area of rooms in a floor plan
Drawing and shading areas to represent given numbers
Each worksheet comes with an answer key for easy grading or self-checking.
4 Error Analysis Pages:
Students evaluate sample student work and determine which area calculations are correct or incorrect. These are perfect for whole-class discussions, partner work, or warm-ups that reinforce problem-solving and reasoning.
Area Craftivity:
Students use creativity and math together by completing a craft that involves calculating area — great for bulletin boards or math displays!
Emoji Math Sort:
Students decide if each task card shows the correct area and mark it with a happy or frown emoji. With 48 cards included, this activity keeps students engaged while reinforcing accuracy.
Hands-On Area Activity:
Students use manipulatives to build and calculate area in a tactile way. Three differentiated versions are included, allowing you to tailor the difficulty level for your learners.
Game #1: Building Block Creations Game:
Students use 20 area game cards to find the area of fun “building block kid creations.” This creative game blends problem-solving with play.
Game #2: Build an Aquarium Game:
Each student gets an aquarium background. Correct answers earn fish or decorations for their tank. The first player to fill their aquarium wins — but watch out for the chance cards that can shake up the game!
Game #3: Whole-Class “Bucket Filler!” Game:
Post task cards around the room and have students travel to each one, solving area problems as they go. Correct answers earn them a ticket for a class drawing.
Game #4: Area Racing Game – “Line Them Up!”
Teams race to place their area cards in the correct order from start to finish. It’s a fast-paced, whole-group review that gets everyone moving and thinking.
21 Area and Perimeter Posters:
Use these visual posters to reinforce key vocabulary and formulas for area and perimeter. They make excellent anchor charts or reference visuals for your math wall.
Every activity is provided in color and black-and-white versions to suit your classroom needs.
This 3rd grade area of rectangles unit can be used in multiple ways:
Whole-group lessons introducing the concept of area
Small-group instruction or math intervention
Independent practice or early finisher work
Math centers or stations
Homework or spiral review
Test prep for end-of-year assessments
The engaging mix of area worksheets, crafts, and games makes it easy to differentiate and keep students motivated while mastering key geometry standards.
